How can I get along with my roommate? (Details Inside)

Just 1 hour ago my roommate was talking in front of me to the big painting in the wall and talking about the blood of Christ. Then he opened a flat refrigerator and closed it and wiped his hand on the paintings and said that he is going to kick his own ass because he thinks that his voices have Asperger’s… He seems to bully other roommates into catering to his delusions of smells in the bathroom.
Also I refused to extra spray the bathroom to the extreme and he asked me to ask the landlord to change my pampers
He is in his 50’s I am 36 all of us are on long term disability.
