I recently did something bad to my friend.
What did you end up doing, and how did this make your friend feel?
It made me feel really cold blooded after what I did to him.
There's no way that you should do something bad to your friend. Apologize to him, or else he may never speak with you again.
I think it was fair what I did to him. He ended up betraying me so I just reciprocated.
But him being friend should mean that you simply forgive him and move on. You trying to get even has only made the situation worse.
