i understand what you're saying, but imo, this misses the point....
by not having harsh punishment, it can easily be argued the government is 'allowing' more deaths, thus, by omission, deciding who lives and who doesn't...in this case, it would be the innocent people dying while the guilty live...
this is not, imo, a case simply of the government "deciding" who lives and who dies, this is about choice and consequences...for example, it is my understanding you are ex military and i don't recall i've ever heard you say anything against the government killing in war or military action....the same applies here....these assholes gave up their right to live when they brutally took the lives of 3 people, not only their lives, but their minds and bodies via rape and torture
if you don't have a problem taking out someone on the battlefield, i fail to see how yoiu can have a problem taking out perps like this
