Many murderers murder openly and don’t get any jail time at all. Cause they are elected politicians.

Other than that - the purpose of the penitentiary system is not to punish people, it’s to redeem them. At least in theory. You don’t have any right to punish other people (well, an eye for an eye may do, if there’s no other way, but that’s the worst that’s acceptable), especially with such intentional destruction as a life sentence.

So your very approach is criminal intent.
