Let me give you the view of a Mormon.
God gave Adam and Eve two commandments. 1) Don't eat the fruit of the Tree of Knowledge of Good and Evil. 2) Multiply and replenish the Earth.
Unlike most other Christian religions (in my understanding), Mormons don't believe that Adam and Eve were able to have children in the Garden of Eden. It was a place of innocence, free from sin and pain, and that includes the pain of childbirth. However, without childbirth, the plan of God to populate a world with his children would be frustrated.
Enter the commandments above. God, being perfectly just, couldn't subject humanity to the pain of childbirth and mortality in general unless they "chose" it by breaking a commandment--eating the fruit of the Tree of Knowledge of Good and Evil. Adam and Eve couldn't fulfill the second commandment, to have children, unless they broke the first commandment.
There's no conflict between the commandments--there was no time limit given on the second commandment, so Adam and Eve could have lived eternally in the Garden of Eden without having children, yet never breaking the commandment. Never fulfilling it as well, of course.
Eve made a choice. A fully conscious, deliberate, logical choice. She chose to break the first commandment, allowing a just God to subject her pain, to allow her to "fall" from her perfect, immortal state to a mortal state and fulfill the second commandment. Adam, being logical, chose to support her in that action.
There was no punishment, no jerkiness, just a perfect fulfilling of God's plan from all the parties involved.
