Yeah but there is a way to come back with memory. Not sure how tho. I think it's a part of a sinister left-hand path. They are somehow escaping the "second death" (the process of losing your energy body) in the astral world, managing to stay at a lower astral level and wait for the suitable body. They are not interested to go into "heaven", so they are sacrificing it for the power on Earth.

That is the secret of the ruling "elite". They are ruling because they cant really die.
