The anime titled “Demon Slayer: Kimetsu no Yaiba” narrates a gripping tale of an unending struggle between righteousness and wickedness. While the heroes fighting for justice are crucial, the villains add depth to their stories. This series introduces several malevolent antagonists, each with a distorted perspective that leads them to carry out despicable acts.

In their fierce battles against the demon slayers, the wicked often expose their peculiar philosophies. Every word they utter unveils either hidden pain or deeply ingrained beliefs. Many of these lines stand out, but here are the most impactful villainous remarks from the show.

7. “We’ll Pay You Back for What You Did to Us”

Gyutaro to Tengen Uzui

Manga: Chapter 88
Arc: Entertainment District Arc

After Tengen Uzui decapitated Daki, Gyutaro swore to retaliate against the Demon Slayer. In his furious rage, he roared out a promise of vengeance.

I will retrieve what is owed to me. Rest assured, we will repay you for the actions taken against us! And as you take your final breath, remember… it was Gyutaro who led you to the realm beyond life!

As I observed Gyutaro’s words during the battle, it was clear they reflected his emotions at the time. However, upon the battle’s conclusion, a darker truth emerged – one that went far beyond just the moment. It seemed the brother-sister duo had endured years of isolation and mistreatment from society in their human lives. The physical and emotional scars they bore persisted even after their transformation into demons.

Gyutaro’s words reveal a deeply resentful character, born out of harsh past encounters that have fueled his thirst for vengeance. He justifies his cruelty towards humans because he believes they abandoned and tormented them, driving him to mercilessly kill every human he encounters.

6. “Until You Die, You Haven’t Lost”

Kaigaku to Zenitsu

Manga: Chapter 145
Arc: Infinity Castle Arc

The battle between Zenitsu and Kaigaku within the Infinity Castle was undeniably one of the most brutal encounters throughout the series. Their shared mentor had been the trainer for both, but the fate of their master, Jigoro Kuwajima, at the hands of Kaigaku’s actions left Zenitsu in deep sorrow and rage. Desperate for answers, Zenitsu confronted the substitute member of the Twelve Kizuki, who was currently standing in for Gyutaro and Daki, about an incident involving Kokushibo that transpired one fateful night.

To ensure his survival, he agreed to transform into a demon and forsake the values taught by his mentor. Justifying his actions, he claimed:

As long as you’re still alive, there’s always a chance to come out on top. Even if you find yourself in the lowest depths, homeless or drinking unclean water, and people accuse you of dishonesty, remember that you can turn things around. You will triumph eventually. I carry this conviction with me.

In isolation, Kaigaku’s words might seem inspiring, but when understood properly, they expose a chilling survivalist mentality. To him, every person he had encountered was merely a piece on the board, to be sacrificed for his own survival and dominance. Remarkably, he never expressed remorse over his significant role in numerous innocent lives being lost. In many ways, he appeared demonic even before Kokushibo transformed him into one.

5. “I Truly Believe That Humans Are Pathetic”

Doma to Inosuke

Manga: Chapter 161
Arc: Infinity Castle Arc

In the grandeur of the Eternal Castle, upon encountering Doma, Inosuke’s heart swelled with powerful emotions. The grim truth that he was standing before a man who had taken the lives of his mother and companions left him quivering with fury and sorrow. He vowed to not only take the demon’s life but also subject him to a taste of genuine torment, a promise that drew a sneer from Doma.

In his typical cold and mocking tone, he said:

It seems unfair that those who strive to live honestly and virtuously often encounter hardships, while the unscrupulous seem to revel in their lives. The concept of divine retribution appears implausible to me. The idea that wicked individuals will suffer in hell after death is laughable. If we didn’t hold such beliefs, it would be challenging for people with fragile resilience to persevere, wouldn’t it? In my opinion, humans often display a remarkable level of weakness.

I’ve noticed once again that Doma speaks honestly, yet his remarks are inhumane. It seems clear to me that he harbors a disdain for humans, regarding them as mere creatures to be exploited and consumed like livestock.

4. “Why in the World Was I Ever Born?”

Kokushibo Reminiscing About Yoriichi

Manga: Chapter 178
Arc: Infinity Castle Arc

Originally, Kokushibo was among the most formidable sword-wielders of his time. His ambition to leave an enduring mark and surpass his brother in martial arts mastery drove him towards demonhood. Yet, despite pouring all his efforts, he felt a profound void within himself. No matter what he accomplished, it never seemed enough compared to Yoriichi’s extraordinary skills that outshone everything Kokushibo had ever attained.

In his last moments, he looked back at his life and regretfully admitted:

Yoriichi, why am I, unlike those who master their paths, unable to reach the same destination? Why can’t I let go and leave things behind, like a home, my family, even my samurai identity? Why couldn’t I become someone notable? Why was I ever born if we are so different in this world?

When Kokushibo’s form crumbled away, a flute belonging to Yoriichi was discovered tucked inside his kimono. This item had been preserved as a keepsake for hundreds of years. His final words echoed with profound sorrow and remorse, shedding light on the chilling truth of being a demon. The immense power he had accrued over countless centuries ultimately proved meaningless, leaving Kokushibo shattered.

3. “I Only Despise the Weak”

Akaza to Tanjiro

Manga: Chapter 148
Arc: Infinity Castle Arc

You misunderstand me. I am merely expressing my admiration for the skill and courage of your comrade.

Tanjiro, you’re mistaken. I disdain the feeble and scorn the weak. I abhor those who are weak. In fact, their presence makes me feel ill. That’s just the way nature works – the weak should perish.

This commentary exposes a chilling mindset, one that suggests the ruthless and destructive intentions of the Upper-Three Rank individuals. He firmly asserts that those who lack the ability to protect themselves may be legitimately targeted for elimination.

2. “And That’s Why I Eat Them All Up”

Doma to Shinobu

Manga: Chapter 141
Arc: Infinity Castle Arc

Inside Infinity Castle, upon discovering Doma, Shinobu Kocho was taken aback to witness him consuming a girl while numerous lifeless bodies surrounded them. Unfazed by the surprise shown by Insect Hashira, he identified himself as the creator of the Eternal Paradise Cult. He declared that his objective was to bring joy to people. Shinobu found his statements disconcerting and attempted to make him see reason by pointing out the absurdity of his actions, suggesting that the girl he intended to eat was in fact pleading for assistance.

Doma grinned and replied, “That’s the reason I rescued her.” Then, he casually explained his actions.

Everyone fears death, but I consume them all, ensuring they live on with me eternally. All the emotions of my followers – their blood, their flesh – are now a part of me. I have taken it upon myself to lead them towards enlightenment.

In simple terms, Doma’s chilling speech reveals the cold-hearted and distorted thinking that guides his perspective on life. It’s no wonder that other demons are skeptical of him and can easily perceive his false kindness.

1. “I Have Never Seen God or Buddha”

Muzan to Kagaya Ubuyashiki

Manga: Chapter 137
Arc: Hashira Training Arc

For numerous years, Muzan Kibutsuji has been on a relentless hunt for his sworn enemy, Kagaya Ubuyashiki. This individual, who leads the Demon Slayer Corps, has significantly contributed to the ancient group’s significant triumphs against the forces of the Demon King. Given this, it is no surprise that Kibutsuji holds a deep-seated grudge towards him and yearns intensely to eliminate him from existence.

Although he tried tirelessly, he couldn’t locate Kagaya until Nakime was selected as Hantengu’s successor and acquired the power to use eye-familiars for surveillance. Alone, Muzan made his way to the Ubuyashiki estate, resolute on eliminating the family that had long been a hindrance in his lineage.

During their brief interaction, Muzan mocked Kagaya for his illness and boasted arrogantly:

I haven’t been made to pay for my actions, as I’ve taken countless lives throughout the centuries. Yet, no divine being has ever shown itself to me, neither a god nor a Buddha, during this long span of time.
