Replying to Neighbor probs

So I have this super annoying neighbor who won't stop being an ass. He plays really loud music all the time, borrows my stuff and never returns it, is always mean to me even though I do nothing but nice things for him and is an all around ass hole. He has a wife 8/10, 2 daughters one 8 yo and one like 1 or 2 and a son who is also an asshole whose like 10 yo. Wife is nice and so are daughters, but son is a dick like him. The only reason I hav't killed him already is because Im somewhat religious and he occasionally goes to church with me. (Even if he does make a fool of himself there and is super disrespectful). I want to get some kind of revenge on him or because Im too much of a pussy to stand up to him. Help NSG what do I do? What do I diddly do?
