If you are suggesting Hitler was persuaded that the Jews were evil, I don’t think that’s correct, he grew up in an environment where many people did believe that but they did not need to be persuaded, just like they did not have to be persuaded into their religion, culture etc. They just accepted the idea without much thought, which does not equate persuasion.
If you are saying the Allies were persuaded that Hitler was evil and must die, I think that may be closer to the truth since they knew the cost of invading Germany would be astronomical, potentially costing their own destruction, and they still stopped only when Hitler was taken, dead or alive. Some serious persuasion was needed for that.
