It's bad to condone bad behavior.
Dave meets up with his friend Bill who offers him a chocolate bar and tells him he just stole it from the store.
Dave wants to respond to Bill's offer of stolen chocolate.
Dave tells Bill that since it's stolen he doesn't want it and Bill should really take it back to the store.
Dave accepts and takes the chocolate from Bill and thanks him before eating it.
Bill is annoyed at first but then realizes what he did was wrong and goes back to return the chocolate.
Bill believes that he can gain status from thieving and continues to do so until he goes to prison.
