According to the Bible those people haven't gone anywhere. When you die you die. Your soul forgets all in the past, your name, everything. You basically stay in your grave in are "non-existent" until Judgment Day.

Also, according to the Bible you have a choice to choose God and Christ, or be on the Lucifer's side when you are called upon Judgment. Those who denounce God go to Hell, and those who ask for forgiveness for their sins and choose God inherit the Earth.

As for the Nazi's and Jews who "helped" in the crucifixion of Jesus, they have the same fate. The same rules apply to everyone no matter how evil or good according the Bible.
