I'm going to disassociate myself from my friends
What makes you want to disassociate from your friends?
I'm going to ruin a person's reputation by spreading a rumor about him
I get the desire to want to hurt someone. But in the end, you end up hurting yourself because of the person you've let yourself become. Really ask yourself if it's what you want to do.
I'm not answering that. I'll do what I want.
You shouldn't do what you want when what you want is to hurt someone. You would hate it if someone hurt you like this, so why be the person that you hate?
