I'm going to extort one of my friends because he made a sex tape with one of my other friends.
Did your other friend know about the sex tape?
My friend didn't know about the tape.
It is not good to extort people nonetheless your friends since it is illegal but it is understandable why you want to do it. It is wrong what your friend did and he should not be allowed to get away with it.
Extortion is wrong but I hate my friend so much and I'm going to hurt him hard.
I don't understand why you would be friends with someone that you hate. It sounds like you need to end this friendship, rather than trying to extort this person. Nothing good can come of extorting someone, especially a former friend.
