Assuming memories and these answers are accurate, I think I’m convinced it’s this guy.

I’m really sorry you have to deal with this shit.

I don’t know what to do about this, aside from arming yourself as best you can.

Now that he’s been notified that his behavior is known to the group, he probably won’t escalate to violence. But the drinking bothers me because drug addiction creates multiple personalities in the sense that the person has a different set of values and goals when they’re using as when they’re not. Sober him could be horrified, whereas drunk him could be willing to do crazy shit.

I’d still recommend contacting whatever your country’s equivalent of the FBI is.

I personally would go talk to him, but I can’t recommend that for anyone else. I tend to be (at times irrationally) fearless, and I have a soft spot for men with dark hearts since I’m familiar with my own dark side. I myself would try to rescue him from his darkness, but I have to emphasize that comes with serious risks.

So to boil it down my advice is:

• Definitely: treat him as dangerous and arm yourself to protect yourself
• Optionally: do what you can to guide him into therapy

Do NOT let your guard down if you decide to help him. It’s okay to help someone while treating them as a real threat at the same time. Love does not have to be naive and defenseless.
