When you're having a conversation with your best friend and they start talking bad about someone else behind their back, what do you do? tell the person or keep it from that person because you know that if you tell that person, it'll ruin your friendship with that friend, and it'll also hurt the other persons feelings?

I would, personally, tell the person my friend is making fun of because of the fact that it is morally and ethically wrong to not tell them that they are being made fun of. I don't care if it will ruin my friendship, it is wrong to make fun of others. I would say the same thing if I went off of just ethics and moral responsibilities.
