Of course it's relevant to that judgement. Whether he and his girlfriend were right to take in and support this guy, and the reasonableness of the rest of the group in cutting off contact do in fact depend on what this guy did. The thing is that we don't need to make that judgement. It's not relevant to the takeaway of "tight friends can have friendship-ending conflicts over unexpected things". I acknowledged this in a response to him. (And, no, from just the original comment, it's not clear he's that opposed to revealing details. Later comments do make that clear.)
