Right

"If your so called-friends urge you to do anything you know to be wrong, you be the one to make a stand for right, even if you stand alone. Have the moral courage to be a light for others to follow."

Thomas S. Monson

What this means to me is that for example a friend tells you your going to steal someones wallet you need to first step up and tell him that is choosing the wrong. Step two would be to not hang out with him as he is a bad influence on you. That action may inspire your other friends to choose the right. Bad friends aren't really your friends. They act like your friends gain your trust and pressure you into doing things that go against your beliefs and moral creed. Those are not the friends you should ever hang out with. Friends who don't steal or do anything wrong and respect you equally those are good friemds.
