So, long story short, I take this girl I'm interested in out with my main friend group. One guy in the group decided to AMOG me and took her home that night. The guy is poison and I don't want to see him ever again.

The problem is, even though the rest of the friend group thinks he was in the wrong, they kind of just want to keep on living and not think about it. I cannot continue to have this friend group if he is still in it.

He is not an "alpha" inside the friend group, in the sense that he doesn't bring a lot of value to the group and it wouldn't change very much if he left. So I think that it should be possible to eject him, but I'm not sure how to go about doing it. How should I approach this situation? Sociopathic answers welcome.
