Someone with a very low frustration tolerance. And anger management issues. And no respect for other people’s belongings. This guy sounds very high risk for returning to the scene of the crime to do more ‘I spit on you’ antics. It’s not so much the damage, I expect, it’ll be more his way of expressing contempt for anyone that he feels is not ‘respecting’ him. Which makes no sense, but I suspect he’s not doing too much objective thinking.

That would make me feel so ick. Throw out your toothbrush. Bleach the hell out of the toilet. It feels so violating to have someone in your house. Hopefully you can talk to someone about how to improve security in the house? Will they provide that in the housing you’re in? Like does it have security door (like this mesh ones)? Lockable windows?
