Some of your reasonings seem a bit simplified. If someone robs a bank, they might want money. Is it because they are trying to feed a starving family? Is their life being threatened due to gambling debts? Or do they just value the safety of others less than they would the money?

And that is the only arguably victimless crime in your list of 3. A crime can be committed by a rational person (if I don't do this, my child dies), and it can be committed by someone who is not mentally well. I would argue that these, especially the last crime, are all crimes likely to be committed by someone who is not in a stable or healthy state of mind.
