Why would you go back in time and kill baby Hitler?

I never understood the morality of this thought experiment. If you had the ability to go back in time and kill baby Hitler, you would essentially be murdering a baby. Does Nazi ideology justify murder and terrorism? Yes? Then you’re a Nazi. The rules against violence are absolute, and if you would kill baby Adolf then you are fully justifying baby Adolf murdering people who disagree with him. <br><br>Hitler is a cross that the world must bear for all non-violent people.
