Do I sin because of Adam?

[junkyardboy]

My interpretation is strictly literal.

So if it is literal, then an omniscient god would know both that Satan would turn on him and that if he did, Satan would lead Adam and Eve to eat the fruit if they were not given an understanding of right and wrong. God knows what will be the result in every possible scenario depending on the starting conditions he creates, so why would he even create Satan if he knew this would happen? If god created Adam and Eve in a way that he knew how they would turn out, would he not have, at the very least indirectly, created their sinful nature?

they were created self willed as is God
