Guys, does it bother you when a male friend of yours is unfaithful to his very sweet wife?

I’ve known women to get mad at their female friends who are unfaithful to a good man.
Good people are hard to come by, either male or female. But I can only say I’ve seen women get upset and sometimes I think it has to do with the fact that, it means their female friend may be out on the prowl and any boyfriend of theirs or spouse may not be off limits to their girlfriend.
But do guys feel the same way? Or do most guys just cheer each other on, seeing it as a guy thing to do, even if they don’t agree?
Does it make a difference if the wife is a friend as well, or if she is hot sexy as well?
Or do you simply have no opinion, just because its not your marriage, even if you are friends.
