There's a guy in my apartment and I'm going to push him out.
Why are you going to push him out?
I want to steal his money.
You should never invite someone over if you have bad intentions towards the person. If you welcomed the man into your home, it is wrong to push him out and steal from him. If you no longer want him there you can politely let him no that something came up and you'll have him over another time.
My plan completely backfired because the poor guy has cancer so he is broke.
You should steal from other people especially if they are sick. It is wrong and you could go to prison for that.
