I disagree with you. The Bible only states that Eve was sinned, not Adam.
I also know that people do wrong deliberately, knowing it is wrong -- challenging parents, the law, God Himself.
Is everyone who runs a red light deceived? Is everyone who commits adultery deceived, thinking "oh, it's all right..."
They know it's not.
The vast majority of adult sins (sins of adults) are choices, not matters of deception.
When you say Satan was deceived by his beauty, then you are saying God deceived him. I reject that entirely. Satan's sin as listed in the Bible was pride and ambition for self aggrandizement.
As far as every person later being in heaven, Jesus refutes that completely. At the end of the parable of the sheep and goats in Matthew 25, Jesus states that the 'goats' will go to eternal punishment and the 'sheep' to eternal life. So however long eternal life is, eternal punishment is just as long...
