fwiw, not every abrahamic religion sees satan the same way. my religion for example understands 'satan' as a literary figure meant to illustrate the extent to which humanity's selfish, maniacal pursuit of comfort can create out and out blithe indifference for the suffering of others.
like i don't even understand why 'good' and 'evil' have turned into these vast theological concepts. 'good' is self-sacrifice for the good of others. 'evil' is self-comfort at the expense of others.
