you have it the wrong way

in previous era's of religious rule.. many thought they had multiple lifetimes(like a videogame) where they dont live great lives in this one because they think they will be rewarded in the next life..
where they didnt live their best life but instead make mistakes and want forgiveness hoping for better life in the next life

however now we see people realise we have one life, so we make the most of it
YOLO=You Only Live Once
