Would it be okay if I took the belongings of a couple homeless men?
Why do you want to steal from someone who is homeless?
I don't know, I can't control myself.
You should really take a look at yourself. It is wrong to steal from people, especially those that do not have a lot to begin with.
I'd rather spend time in jail than give up on my impulse control.
Why would you rather go to jail? You would be forced to give up your impulse control while in prison, so either way you will need to calm down. While not do it while a free person?
