There was a meme a while back that said something to the effect of "if you were to kill someone, not only would I not tell, but I would help you bury the body." In a joking sense, this speaks to the lengths one would go to support a close friend. Unfortunately, this time of followership is sometimes not far from the mark and prisons are full of people who showed misplaced or blind loyalty and served as accomplices or accessories to crimes. Sometimes it is more subtle. Sometimes friends stand by and watch friends or loved ones continue down a path of self-destruction.
True loyalty is sometimes tough. It is telling the friend not what he or she wants to hear, but what he or she needs to hear. It can be awkward, for example, "hey, you should go to the restroom and clean your nose." Yet the receiver of such feedback would much rather hearing it from a friend than walk around all day and be the subject of ridicule. This is a simple example, but it could be applied to drug use, bullying, or any other self-destructive behavior.
True loyalty is not supporting one's friend to be at his or her worst, it is helping the friend to realize his or her best self.
