Hitler murdered a lot of people.
Can we stop a lot of murdering by trying murdering him?
If yes, then it justify murdering him.
Jew here.
No, your logic is flawed. The only way to be able to do what you have posited is to have known before hand that Hitler was going to do what he did, or perhaps to travel back in time. either way, unlikely.
I believe that the only justification for killing, at all, is in defense of your own life ro the lives of others, and even that only when it is absolutely necessary. I would not have killed Hitler, I would have captured him and left him to rot in a prison for the rest of his miserable existence. When you give in to vengeful thoughts, and say that you can justify killing because of someones actions or behavior, you sink to their level. I am against capital punishment because the idea of "If you kill someone, we will kill you back" is so utterly ridiculous and juvenile that any rational person should reject it. That is the mentality of a fucking third grader.
