I believe that I'm going to give my roommate a taste of his own medicine
That sounds questionable, what did he do to deserve revenge?
He's been complaining about me being rude to him.
So you're going to be even more rude because he's called you rude? You shouldn't fight fire with fire and maybe apologize.
I am going to fucking ruin his life.
I understand that you're frustrated, but I would rethink your planned actions. Getting revenge is generally a waste of time and you should assess and look at the situation from your roommate's perspective. Apologizing is probably the best solution in this scenario.
