According to the many worlds interpretation of quantum mechanics, where multiple(a very high number) possibilities are realised, can there even be a basis for morality in some particular branches?
If taken completely at its face value, many worlds leads to possible worlds where a person is the worst possible version of him/her self, committing the most heinous crimes imaginable. Also to a world where every person is encouraged and rewarded to inflict the maximum harm possible on others. For the sake of argument, lets consider it to be a world full of people that by the standards of today would be extremely horrific, a population purely dominated by serial rapists,torturers and murderers, with rampant slavery and every thing we consider inhuman.
Our world has experienced all this but has gradually become a lot better. But lets take the branches in which the arc goes in the opposite direction i.e things keep on getting worse.
Should it just be taken as a by-product of a possible theory?
Or is there a way to make sense of morality in this picture?
