I figure living until the heat death of the universe would give you enough time to process that kind of horrifying inevitably. Or give you enough time to figure out if there's any way to kill yourself
Immortality with absolutely no way to kill yourself is horrifying. I think suicide/dying is an essential part of life. I would much rather die than be stuck in an infinite void...
I think I'd still trade that for the chance to live and experience shit loads before the horror but yeah it is horrifying. Then again some people live thinking the afterlife can be endless torture anyway. I'd rather have endless nothing
