If you're going to talk morality you have a similar problem. Every moral system I've ever seen has an enforcement mechanism, and it's always the same: if somebody starts acting immoral, you "get to" violate morality towards this person. You get to violate rules to stop the problem. Normal restrictions, against violence for example, are lifted. And without anyone's permission, by the way. YOU have to judge for yourself if you're in such a situation. There is even tolerance for some reasonable amount of collateral damage.

Example: Somebody starts, or even threatens, to kill a child, you can empty a clip of bullets into them. You can break their bones. You can hit them with a bat. Hard. That's fine, sometimes even described as "heroic".

And if you empty a clip of bullets into a random person, well, that's against morality.

You can do a lot of things to such a person that would never be acceptable under normal circumstances. In fact, in western countries, violating normal rules to prevent worse outcomes than those rules are meant to achieve to is a duty. This goes from being forced to help if someone's in real trouble to if you are blocked by a red light and refuse to violate the law and prevent an ambulance's passage, that's a serious crime.

You read that right, under those specific circumstances not violating the law is a serious crime.

There is no moral or legal system that has an absolutist view like your statement makes. 12 year olds think like that. And of course, if you actually read this law, you won't find such an unqualified rule.
