This has occurred a few times in Black Butler.He simply had no concept of what being a good person was, and part of himself hated that. After the kings death, Kenny made it his ultimate plan to become the Founding Titan so he could inherit Uris memories and see what being a selfless person would feel like. However, he was intrigued by the apparent selflessness and goodness of his friend King Uri Reiss. He is an infamous mass murderer who loves killing more than anything and even refers to it as his hobby. Kenny the Ripper takes this trope to the extreme.Reiner agrees that he's a monster, and later refers to himself and his allies as short-lived mass-murderers. While unleashing a You Monster! speech against Reiner and Bertolt, Eren states that their crimes mean neither has any right to human emotions like guilt or remorse.

When paranoia breaks out in the court room and someone accuses Mikasa of not being human, he lashes out by stating that he might be a monster but she has nothing to do with it. During his trial, Eren is repeatedly accused of being a monster.In Attack on Titan, this happens more than once.A recurring motif in Armitage III: the titular character feels like "some kind of monstrous doll" for her robot nature, and has salt rubbed into those wounds by other characters repeatedly calling her a monster when they become aware of her non-humanity.
