In our humble opinion, Atheists end their lives without a God, which will lead them to Satan in the end.
(Story of Atheist College Professor who saw hell in his NDE).
Atheists Near Death Experience - Seeing Hell. He died while scuba diving and bitten by jellyfish.
Buddhists, Idolaters, and those worshiping false Gods (such as oceans or trees or money).
Story of a Buddhist who went to hell in his NDE:
What many do not realize is the Gods they worship: Statues, money, Buddha, they are related to the entities in hell - those entities did not choose Christ and are in hell and they try to captivate and take control of your lives by moving you away from Christ.
Muslims believe: They worship the God of Abraham, Ishmael, and Jacob, and God had no Son, but Jesus was a good man.
Jesus said to this Muslim: I am the God of the Christians: I am the God of Abraham, Isaac and Jacob. He is God's son. Don't be fooled into living a full life while serving the wrong God.
