Might I offer another perspective on Adam? I know that this will be different from what some believe, so it is only meant as something to think about, okay?

In the Garden of Eden there was no death, and no understanding of what death was. There was no knowledge of good and evil. The animals, and Adam, were all innocent. God created Eve so that Adam would have a companion. They were placed there in the garden, to enjoy the garden, and were given a commandment to multiply and replenish the earth. They were also told not to eat the fruit because they would surely die. They probably had some idea of what that meant, but how can you really comprehend it in a world without death? Also, in that immortal state, they weren't able to have children, so they couldn't keep that commandment.

The serpent convinced Eve that something was missing, and persuaded her to eat the fruit. She did that without cunsulting Adam, or God, and then she told Adam what she had done. She was still alive, but knew she would be cast out of the garden. Adam had quite a dillema on his hands now. Don't eat the fruit. Multiply and replenish the earth. Can't keep both of those - no way to have children if Eve is cast out alone. But she didn't die (yet - she lived on for hundreds of years), So he chose the best that he could, and ate the fruit so that he would be cast out along with Eve, and they could keep the higher commandment.

Sin and transgression are not always the same thing. Adam transgressed the law, but it wasn't out of evil or malice or even weakness. He made the best choice he could make. Punishment and consequences are also not necessarily the same thing. Laws have consequences which must be kept. Adam and Eve brought death (and transgression, and knowledge of good and evil) into the world, since that was the consequence of eating the fruit. Now they were mortal, and could die, but they could also have children. We never lived in the Garden. We were with God in the pre-mortal existence there, waiting for our turn to come down to earth. If Adam and Eve had not done what they did, they would never have died, and we wouldn't either, but we also never would have been born. What they did was for us, and was part of God's plan. That was where the serpent was confused. "Adam fell that men might be." (2 Nephi 2:25). Adam gave us mortal life. Mortal means having to do with death. Jesus gave us redemption and immortal life.

Just something to think about.
