Dealing with a religious psycho professor

I have a graduation paper and the main person in my committee  is the biggest religious psycho u cant think of
He shitspams me with religious shit all the time, committed to prove I'm Satan himself. Also, he's trying to use me as his clown to spy and rat on people, esp. on my best friend who he seems to despise. As I wont tell a thing about anything and I'm constantly blocking his ass everywhere, he's dedicated to ruin my life and a graduation paper
I did a little black magic and found pics of other professors wifes on his mobile
So.....what should I do to the religious boyyy?
