You claim you have the perfect defect to child abusers who kill babies and little children - because their lesser health and smaller size was "a contributing factor."
The reasons that you keep giving are so blatantly and understandably wrong, and so contrary to every application of law in relationship to assaults it seems clear at this point that your messages are using satire to really argue the opposite of what you are posting.
Here's the fact. If you assault someone you are liable for the consequences of your assault. Your incessant justifications trying to blame the victim does not work. It has never worked. There is no theory of law by which it works.
Thus, of the many reasons you should not violently assault someone is that the person may have medical conditions you are not aware of, by which your assault may cause more injury and have consequences other than you intended.
Unlike what your view of "blame the victim, not the assailant!" defense, it doesn't work.
