If joesph Stalin and mao zedong killed more people than Hitler, why is hitler hated more.?

It's not simply a numbers game! Intention counts as well as outcome - at least, I think it does - if you are examining the matter of human evil. Stalin and Mao were tyrants and mass-murderers, but their ultimate goals were not murder but liberation.

They aimed to create a utopian state - and while their methods were mad, we can at least admit that their aim was somewhat attractive. The Third Reich, on the other hand, was motivated by an ideology of racial hatred and national supremacy, which entailed the extermination of other peoples - not just Jews, but also Slavs, Romanies, and many others. You might not see any moral difference between these two positions, but I think it is possible to give some qualified approval to the aims of Maoism and Stalinism, while deploring their means, while viewing Nazism as a thoroughly evil and anti-human ideology.

Of course, I doubt it makes much difference for the people who died. There is, however, the matter of the other side of the ledger: what good did they achieve? Both Mao and Stalin dragged their nations up from poverty, industrialised them, urbanised them, and set them on a path to greatness.

Hitler destroyed not only his country, but half of Europe. For that reason, any historical assessment of Stalin and Mao has to admit their achievements as well as their crimes. Hitler's only achievement was burnt wreckage.

Hitler had a policy of genocide, that his objective was to kill but for Stalin and Mao the killing was a side effect of their policies. We make the same distinction for lesser murders, for example the Boston Bombers are more hated than some one who kills and injures people while committing a crime.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
