Now THAT dude sounds like a real nut . . . a little bipolar are we there, god?
Everything which comes as a consequence, from the harmful natural environment, through pain suffering and death, is a consequence of human choice. The only way god could have prevented this was by eliminating humans ability to choose, then we would not BE humans, we would not be able to grow, mature, evolve, learn, and become.
God knew there was a risk, but he took a punt on us. We let him down. But we also have the chance to make it right again. In the bible story, every human who accepts this chance is restored to immortality and the life of eden. Sounds a fair deal to me.
In the less allegorical world, every human has an individual chance to make earth a heaven for them selves and for all, but we also have the opportunity to consign it, and ourselves to a living and very real hell on earth today.. Today some people on earth live in an edenic heavenly state. Others live in hell. It is all in how and what you chose.
