What if I steal $500 at the shopping mall?
Why would you steal? What would you do with the money?
I'm going to buy illegal stuff like weed and cocaine.
Stealing money from anyone or any place of business is really wrong. If you're looking to get money you should try to find odd jobs to do around town. If you go down the path of stealing the money you most likely you wind up getting arrested.
I will only steal the one time and then never again.
Doing something illegal once could ruin your entire life, it could come with a fine up to one million dollars and years in prison. Could you handle any of those things? If not, then I think you should stay away from it!
