The issue of a god or gods is peripheral, IMO, because there could be a god who decrees that we should not be too much of a burden on others, and that getting oneself out of the way can be a merciful act.

What is more relevant here is the question of an afterlife. If the next world is so much better than this world, then why not depart from this world by committing suicide? That is why the theologians have decreed that suicide is a sin, that it is gate-crashing, crashing the Pearly Gates.

Even aside from that, why not try to have a quick and painless death? If one's body is no longer a good home for one's soul, then why not move out before it becomes absolutely unlivable?

it's the old story: everybody wants to go to heaven but nobody wants to die.
i despise those hypocritical religious fuck ups that won't leave until they've been laying in their own waste for months & have cost our healthcare system a lot of money which could have been much better spent.
there was a case in winnipeg in which a jewish man was terminal but the family would not agree to have him unplugged even though he was vegetative & they had difficulty keeping bed sores from his body which smelled badly.. it got so bad that a highly respected young doctor couldn't stand to have anything to do with this patient & family so he resigned.

The only way that religion can affect this is by its ban on managed death, but that tends to be expensive anyway. If the care centers run by religions overcharge then that is a simple matter of stealing.
