If he's regretful, treated and paid his time? Yeah I think so. It didn't show particular signs of cruelties and he was legit insane at the time. Harboring grudges, even if justified, for decades and making it your lifelong mission to keep following and resenting and attacking a person means your life will also be stuck in that day.

Doesn't mean I'm going to personally embrace him and invite him in my house like some people do.
