True, and I didn’t mean it in a necessarily derogatory way in terms of judgment for his mental illness, but for his actions. I know I should be more careful about saying things like that, and didn’t mean to imply anything negative about people who struggle with mental illness.

It’s complicated. Nobody should have had to go through what he did, but something awful somebody went through can’t be used as a justification for them doing something awful to somebody else. It can be the reason they did it, and it may arguably make them not fully responsible for their own behavior, but it also doesn’t make them an innocent if they harm someone else.
