or maybe you guys will just go to hell to be reincarnated regardless of sins/etc, just like asian culture if i remember correctly, it's say that after u die, u will go to hell, where an old lady will make sure that u drink a soup of hers that will erase your memory, after that, depending on what u did in life, u will be reincarnated accordingly.
So, if u are a mass murder, u will reincarnated into a puny insect, maybe u will be stuck in an never ending cycle of reborn as an ant, 1 sec later, gotten stomped, reborn again as an ant, rinse and repeat.
Maybe if u are good, they will let u choose what u want to reincarnated as, who knows though, but i wish that is true, if so, i will dodge the soup and try and aim to be incarnated as ultraman or a mask rider or a zombie, who knows what i might have to do to make that come true though.
