You made a good argument with these points.
Well, there are some crimes that are justifiable if you look at the reason for committing such crimes. For example, the case of murdering a person who wants to kill you. Yes, it is a crime, but a justifiable one, and also, the person who steals without any reason or just because he loves what he sees should be punished, but a person who steals because he wants to feed his hungry family, there is a reason for it. No crime should go unpunished but the reason for each crime matters a lot when handing out punishment
