While still retaining his sadistic and maniacal personality, he is capable of showing remorse. He is shown to hate himself. In many timelines, he wishes he was not existing as it would take the pain away. He despises the monster that he is, not wanting to be a monster who kills for satisfaction.

I'm currently not in the mood for killing you today, so you're spared... For now."
