Thanks, everyone, for taking the time to post.
It definitaly is partially a chemical imbalance. The guy went crazy from drinking too much water (that’s what makes this so sad) and is now living where I live. Unfortunately, if he’s kicked out, then he will very likely die on the street. He’s willing to live on the strett, and he knows the life, but we know that it usually ends badly
The people who love him want him near, so that they don’t lose him. I’m living there as “protection” for them. He’s only been violent against material objects, and always in a temper-tantrum way. Unfortunately, he does seem very rational, it’s just that he loses him temper.
The craziest part is that he’s an avid trainer and martial-artist. I’m the only “protection” these people have if the scenario turns bad, and I really doubt my ability to subdue him. Hence the estrogen.
Hey, my idea isn’t too bad. My other friends (who know a bit more about the scenario, obviously) have suggested putting ground glass in his food. Just enough to give him internal bleeding. Obviously, I can’t really do that.
The other people think that he’ll “turn around” some day. I don’t. I’m just trying to think about a way of being pro-active in our defense without resorting to illegal means.
