Literally nobody would be left. This is big issue with our cultural moment right now. In the past, it was understood that all humans are fallible and worthy of forgiveness. The standards seem to be so unrealistic right now that it is making everyone miserable. This is not to say there should not be accountability. But there should also be proportionality and second chances.

Who's morals exactly? There's a big difference between following the morals of a traditional religion and following the morals of some retards you happen to align with because of your pre-existing lived experiences. Organized religion solves the individual morality problem of having an over-arching unified set of principles everyone is aligned to by making morality something that humans can't change.
