I'm going to make my entire class hate my friend
How do you plan on making your classmates hate him?
I will anonymously post some embarrassing photos of him on facebook to get even with him
Well, that would be too mean. You will also get in trouble for it. Is he worth the trouble to you? Think about it. Years from now when you have your class reunion things will be awkward for you all.
I have nothing to lose, there's no loser in this situation. It was all Plan A. I just wanted to see the effects of my actions.
I would just forget it and move on to save yourself some time and energy. Trust me, it's better this way.
