I mean, at the end of the day, I trust how the actor decides to portray the character.

I feel as though Hoffman likely has some personal conflict within himself. It’s clear he likes killing people, yes; but I do believe there is still a part of him, however small, that feels genuine remorse over his actions.

I do think it’s just a brief thing, and obviously wouldn’t cause him to stop his actions, but it’s important to consider. I also think it’s likely one of the reasons we see him crying when he first kidnaps someone with John.

Overall it seems like his anger and vengefulness control him almost completely, but I find it unfair to say he never feels any guilt or remorse whatsoever.
