Assume there is divine justice.
Hitler slaughters 6 million innocent Jews in WW2. How does Xian/Mohammedan soteriology work here?
It appears that as per Xity, if Hitler asked for forgiveness on his death bed, all would been forgiven. So, all Hitler had to to was "accept JC as his personal lord and saviour".
Likewise, in Islam, had Hitler pronounced "There is no God but God and Mohammed is his last messenger" before breathing his last, Allah would have forgiven his sins and provided him with unending bliss [and 72 you know whos] in heaven.
Thus, an Abrahamic faithful in her afterlife has every chance of meeting Hitler in heaven.
I find this absolutely disgusting. If I were to meet Hitler in heaven, I would have serious issues with the God. There is no way I am worshipping a God that provides a chance for Hitler to so easily enter heaven.
Hitler's crimes HAVE to be worked out via Karma. That is justice. We may not know how exactly Hitler's soul pays for Hitler's crimes. But that is an epistemological issue. We dont NEED to know the details. Per Karma, his soul WILL pay. That is guaranteed.
