I'm going to kick out a jobless friend
Why are you going to kick them out, is it because they're jobless?
I know he is carrying a drug habit and stealing from me
It may be immoral to kick your friend out in this difficult part of his life. Maybe waiting until he is able to find a job would be the better option, but give him an ultimatum.
You're just going to let me be homeless because of a junkie.
No, I just don't think you should kick him out automatically. Is there a way to get him help? Have you tried to call a rehab center?
