Hi. So, you say, "If someone is in the wrong.. even a friend, I am on board letting them get in trouble. I mean, I would warn them but..." - which means you didn't actually warn them and you let them get in trouble. Yes, I think most people would perceive that, in the long term, as being neither a good friend or loyal. Part of loyalty, I believe, is standing by the person even when they falter. Of course warn them, but stand by them as well. This is all just theory of course.
