... Ehhhhhhh... God's pretty evil, mate. Biblically and via creation. Worlds kind of shitty and in lots of evil ways. Disease (and the really horrid ones, like worms in your veins and eyeballs, or your muscles and skin literally turning to bone, trapping you in a cage of your own tissues), natural disasters, 99.99999999% of the universe being inhospitable to life as we know it (human life especially), the favoritism of a tiny tribe in a backwater region that's only redeeming resource wouldn't be relevant for thousands of years (and even then, Israel doesn't have much oil if any )
He's kind of a wonky dude. If not evil, not exactly "father knows best" good. I'd steer clear if I heard of an actual person with his track-record.
That is all mankind fault. If you want to point fingers, you can blame Eve, but we all have sinned. There was no disease, death, or pain before that.
But we didn't create diseases, or vile parasites, or dangerous weather. Even if your creation story is correct, God created all of those, and not even in response to Eve's mistake. None of those are mentioned in Genesis 3. One could suggest diseases and parasites were introduced along with mortality, but I don't see anything that actually says that. Creatures were all specifically created earlier, presumably including parasites like tapeworms and nasty insects. Arguably infective bacteria and fungi as well.
God's curses were:
3:16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
3:17 And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
3:18 Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;
3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
... Is it just me or did women get the bad end of that deal? Everything God did to man, IE hunger and mortality, applies to women too (though the language here amusingly doesn't *say* that). Whereas women also get painful childbirth and are cursed to desire and feel submissive to men. (Free will is soooo important to God, isn't it...)
I guess it's intentional since she's the one who convinced Adam. Even though she had no concept of right and wrong, and was
convinced lied to by a celestial being, and Adam agreed to do it.
I do love that a strict reading suggests that Adam gets mortality and a malus to farming, while women don't. I'm imagining Adam going hunting or goofing off while Eve farms, since he's cursed to suck at it (and she's cursed to enjoy serving him). And then both of them being super surprised when she dies.
Edit: And though I mentioned this last time, it bears repeating:
3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
God did this to all of us, forever, deliberately. Punishment is only just when it prevents future crimes by exclusion or rehabilitation, and it's never just to apply it to uninvolved parties like descendants.
