So, God creates a garden for Adam and Eve, where he purposely puts a tree with forbidden fruit. He also puts talking snek with full knowledge (omniscience, remember) what it will try to do. And when it happens, boom - cancer for children for generations. Such a benevolent creature this God personage. Even Omnibenevolent, I would say.

Eve: eats some apple God: That apple stealing whore!

Beacuse some woman led that man astray to eat the apple...don't forget the masogeny

If Adam can curse the whole human race without their involvement, why can't Christ save the whole human race in the same way? Paul almost says as much in Romans...

18 Consequently, just as one sin (Adam's) resulted in condemnation for all people, so also one righteous act (Jesus Christ's) resulted in justification for all people. 19 For just as through the disobedience of [Adam] the many were made sinners, so also through the obedience of the one man [Jesus Christ] the many will be made righteous.
