According to Beetlejuice, they become public service in the afterlife

I don’t know like most energy does it transfers. I also was raised to believe that suicide is a sin, but I think they use that to detour people from committing suicide.

Its against my religion to commit suicide, so I dont know the answer to this question . However my religion does allow death by natural causes, and again it would be like going to sleep but never waking up.

I don't look down on people in pain. Healthy people have a strong will to live. My faith has hope from them.
