Batman. He’s a billionaire playboy living in a city full of poverty. He may not kill but he has no problem crippling someone for life. And the fact he apparently learns nothing about the joker over the decades has resulted in so so many people dying to the joker’s schemes.

And the reality is that he’s still that same child in that alley but in an adult’s body. He takes on different child robins because he never grew past that. He has trauma that was never treated and one of the main symptoms of trauma is being stuck in the time period that the trauma happened. He doesn’t really have a personality beyond the trauma.
