These are the occasions I wish death penalty was a thing, especially for those cases where the idiots have been caught in the act - there are better things to do with my tax money than making sure they have a place to live in and some nice good meals to go with it.
I do understand how you feel about that and I do kinda feel the same, BUT ... you always have to assure that every last person has rights and gets acceptable treatment, even the ones who seemingly have no soul. Because if there's ever a category of people without rights, any government would have an easy way to get rid of eveyone critizing them.
Isn't being jailed forever also an "easy way out"? I'm sure there are people on this planet who are not in jail, but, because of too little money or other circumstances, have less and get treated worse than people in jail.
Also, if being alive really is hell to you, you might want to do something about this.
[edit]
It seems this has been unclear. By "do something about this" I meant speaking about the problem or therapy or the like. Yes, life sucks some times, but if being alive is hell for you, you got a problem to fix.
