"I'm God, your great great [...] great grandmother did something i didn't like so i hate you and plan to torture you for all eternity. Please execute me slowly and painfully so that i can forgive you!"
We live with the consequences of Adam's sin (death) which is a mercy because it means we can become sanctified and enter the kingdom of God instead of being eternally fallen. God loves you but hates your sin. God does not torture you. The experience of God is heaven for those that are sanctified but hell for those that are not. A poor analogy would be that a football game is the same for everyone but only those for a certain team are happy with the outcome. (Just to give an idea of how a shared experience can be different for different people) Finally Christ didn't ask anyone to execute him but he knew they would. He lived a perfect, sinless life. His death allowed him to enter hades and conquer death thereby freeing man from the damnation of sin and grafting all of mankind into the new covenant which allowed all to be saved through Christ.
(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: (23) Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
Had they eaten the fruit of the second tree, then they would live forever, they were already mortal.
Genesis 2:15
But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
A bit weird to get mad at someone for doing something bad/evil, when they literally didn't know what good and evil was and thus wouldn't know that disobeying god was a bad thing.
And also strange that god lied here, seeing as they ate the fruit and didn't die (yeah yeah "spiritual death", why wouldn't god just say that if that's what he meant)
