Religions that support reincarnation is one, though most would say you get reincarnated as something more/less favorable depending upon the life lived.
By no stakes above, I was mostly referring to an eternal amount of time to do anything, supposing a bit that one could accomplish a lot in many of the version of afterlife I've heard of. I wasn't thinking of it in a 'no morals' or similar way, but I can see how it could be read as such.
