It’s ok to think this guy is a piece of crap even though he’s the landlord. If someone doesn’t pay their rent, then kick them out. But that doesn’t give you the right to act like a mental case and try to kill them.
I don’t think he was trying to kill them. Instead I think he was trying to scare the crap out of them and also render his property uninhabitable so they would have to leave.
Say you hold a mortgage on the rental property and you're making the payments every month, but your renters aren't, plus you have your house mortgage you're making payments on, and you have been trying to evict the deadbeats for two years and now you can't make your payments anymore and you are about to be evicted yourself.
But it's easy to be self-righteous when it ain't your skin in the game.
