They said that violence did not solve anything, but in the anime Shōnen, violence tends to help. As a result, it created some main characters that did not hesitate to become violent.
10. Taro Sakamoto – Sakamoto Days

Violence means a person who is willing to hurt others for one reason or another. Taro Sakamoto used to be a good assassin, but it all changed when he met Aoi, who proved him that all life was valuable.
Taro then quit the assassin to become a salesman at the convenience store. Even when he was in middle age, there were many people who came to revenge, he still complied with the principle of not taking his life. He just defeated them without finishing.
9. Kamado Tanjiro – Kimetsu no Yaiba

If Tanjiro's fate depends on him, he may still work as a family's coal burning. But after his family was murdered by the Demon, his kind personality gave way to the need for revenge, leading to him to become a swordsman.
When witnessed that ordinary people could also become a devil, and there could be a way to turn them back, Tanjiro's wrath was calmed down. He will give mercy for those who repent, and can even help them. But for those who do not repent, like the Demon King Muzan, all he has for them is just his blade.
8. Goku – Dragon Ball

In Dragon Ball, Goku can move wars to areas without people to avoid harming others, but he always has a brutal aspect filled with anger.
For example, the first transformed into Goku's super Saiyan. Earlier, he was able to destroy the entire Red Ribbon Corps himself as a child. It is the carefree attitude and intelligence in fighting is the way he controls that angry Saiyan, instead of letting it control him.
7. Day Giovanna – Jojo's Bizarre Adventure

Jojo's Bizarre Adventure never dodges violence, although it may be difficult to determine who is the most violent protagonist in the 6 Shōnen parts (7 and 8 are Seinen). But they rarely target the enemy's life to achieve their goals.
Giorno Giovanna of part 5 is another story. He tricked Polpo chewing the gun head, making sure Melone died of snake bites, given Cioccolata (7 pages in the original manga), and convicted Diavolo to suffer from losing his life.
6. Akame và Tatsumi – Akame ga Kill!

Akame and Tatsumi are the main character duo of Akame Ga Kill! Akame has been trained from a young age to become an assassin. Therefore, she never hesitated to swing the Teigu Murasame sword into her enemy, because it could take the enemy's life with just one slash. Tatsumi is less likely to take people's lives, unless provoked. For example, when he discovered his friends were tortured by Aria to death, Tatsumi stopped Akame … just for him to be able to do it on his own.
5. Denji – Chainsaw Man

Considering that he is the main character in Chainsaw Man, Denji may be a rather violent guy. Being forced by Yakuza to repay the deceased father, Denji collaborated with the Devil Chainsaw like the dog named Pochita to hunt the devil. Later, to save Denji's life, Pochita fits him, connecting the two and turning him into a hybrid between the devil and the person.
By pulling a rope on the chest, Denji could become a machine -headed demon and defeat the demons raging in Tokyo. Denji tried to live a normal life and gave up the days of reeling with the saw. But he was used by others as a violent executor for one reason or another.
4. Kenshiro – Fist of the North Star

Kenshiro in Fist of the North Star is probably the most classic example of the main character in the anime Shōnen too violent. Leaving to death after his fiancé, abducted by his former friend – Shin, he found the reason to become brutal in the brutal time.
Good and honest people do not have to worry about suffering at Kenshiro's hands. But anyone who is evil will suffer fate worse than death if Kenshiro touches them. He is very happy to let those who do evil to taste their own poison ten times.
3. Akira Fudo – Devilman Crybaby

If Kenshiro is the ancestor of super violent Shōnen heroes, then Akira Fudo is a great ancestor, inspiring Kenhiro, Bersern's Guts and many other Anime antagonists. His kind and meek personality blends with the personality of Ammon devil to create Devilman. In this form, he became a scene of tearing the body of other demons brutally, but there was still enough humanity to keep him on the path (relatively) righteously. However, it was not enough to save him from death, because both humans and demons were wiped out in the end.
2. Light Yagami – Death Note

When people think of violent protagonists, they rarely think of those who promote conflicts, let others fight and die while they sit comfortably at the desk. Although Light Yagami is not a fighting expert, with Death Note, he can easily take many people's lives.
After gaining control of life and death through Ryuk's special notebook, Light began to use it to decide who would live to witness his “new world”. Taking the nickname “Kira”, he won the admiration for seeing off the worst criminals being detained after iron to the sky. But he soon expanded his list of deaths to include those who came too close to find him and prevent his wildness.
1. Eren Yeager – Attack on Titan

Eren managed to perform an almost global extinction with humanity. With the power of Titan Thuy To, Eren used vibration, which made the giant Titans destroy 80% of the human population to save Paradis Island. The goal is to prevent any Titan from being created. But there is an opinion that the Titan curse still exists after Eren's genocide.
