Jehovah's Witnesses: Is there any real punishment for the wicked?

I am not a JW. Your question has a couple of flaws. Hitler will be resurrected. Resurrection is what Jesus made possible and it is for the "just and unjust." He will be resurrected and he will be judged by God for both his deeds and what was in his heart. If God finds him to have done evil and there is evil in his heart, then he will be punished. The greatest punishment will be not getting to live with Heavenly Father for the rest of eternity. Imagine what that would b like for Hitler, to watch the 6 million people he killed receive greater rewards than he does for eternity. To realize that he blew his chance. WOW.
