Imagine actually trying to make people feel bad about Hitler and Pol Pot.
Edit: Yes I am aware that they are not actually Hitler and Pol Pot, but they still slaughtered a bunch of people. Them smiling in their final moments does not redeem them.
It seems you don’t get it, although the title says “reincarnation” they are only the the incarnation of the “greats”. They have their abilities but not their personality nor memory.
