If Adam chose God over Eve, what would have happened to Eve is one of those hypothetical questions that gets asked on a regular basis. While we are sure he wouldn’t have made Adam suffer the results of sin, we’re really not sure what would have happened to Eve?
We’ve probably got two or three options. The lord may have enacted the plan of salvation for Eve because he loved both Adam and Eve equally. However, this is all speculation which is worth nothing. To be blunt it’s a tough question that can not be answered.
