Do all other Religions besides Christian go to hell?

I know Christians, Jews and Muslims do. Of those who died in the Holocaust many went to heaven. Just as there are many Jews now who go to heaven. They are the Messianic Jews. I even support an organization called Jews for Jesus where they witness to their people about Jesus. At least 5 million Christian were also slaughtered in the Holocaust. I'm sure many of them witnessed to Jews while in those concentration camps. You should read the book, The Hiding Place by Corrie TenBoom. She and her family did all they could to help many Jews and ended up dying in concentration camps with them. Corrie is the only survivor of her family.
