Adolf Hitler

[PanzerJaeger]

I have never read any solid evidence that he ever personally killed anyone, which matches his character. Unlike many other dictators who relished in killing their perceived enemies, it was always a sacrifice Hitler made for Germany. Hitler did not want to kill off the SA leadership, but their split with the SS threatened the party and his vision. Hitler did not want to kill off the Jews, but they were infecting German society and the Allied nations would not take them. He saw himself as making necessary decisions others were too weak to make - a good man suspending his morals in a time of great national crisis. The psychology behind it all is fascinating.

Your best bet is WW1, but his task precluded much time for engaging the enemy. Runners often did not even carry rifles. I haven't read Mein Kampf in many years, but I do not recall him mentioning killing people.
