As a result, his personality hardens dramatically, and he becomes capable of hurting others for his own personal benefit.I think Claymore should be here too.

The experience leaves Kaneki so physically and psychologically broken that his old defense mechanisms no longer work. Oomori employs a variety of inventive torture methods, such as repeatedly cutting off Kaneki's fingers and forcing them to regenerate, or putting a Chinese red centipede in his ear. Ken's demeanor changes dramatically after he's tortured by a ghoul named Yakumo Oomori. Instead, he represses most of his actual emotions (after an initial freakout), and convinces himself that his circumstances are acceptable. That all sounds pretty rough, yet Ken doesn't actually react that strongly to the horror. In Tokyo Ghoul,the hero is subject to a not-so-great home life, and winds up being brutally attacked by a man-eating ghoul whose organs fuse with his own to create a ghoul/human hyrid that needs to consume human flesh to survive.

As a side-effect of this, Guts regularly finds himself acting violently towards his loved ones, despite his best efforts to remain calm. Guts is deeply scarred by his past, but considering how the world of Berserk regularly features religious zealots being burned at the stake, there probably aren't too many qualified therapists hanging around. How does Guts deal with this his life of trauma? He becomes a miserable, hard-hearted man who will stop at nothing to achieve revenge. Later, Guts survives a terrifying supernatural event called the Eclipse that leaves him severely injured and branded with a mark that attracts dangerous supernatural forces.

From there, he's adopted by a mercenary named Gambino who regularly beats him, and eventually begins advertising the young Guts's services as a sex worker.

As a newborn, Guts was found beneath his mother's hanged body. Guts of Berserkhas arguably one of the worst childhoods in anime history any one of the horrible things that's happened to him would completely wreck a normal person.
