Adam and Eve were given the choice to choose what 'fruit' would be part of mankind's existence. Your philosophy is that this was the wrong choice, and God should have punished them--but no one else. That is not Biblical philosophy. Biblical philosophy lays out the possible courses of actions first humans had to choose for all of mankind. God counseled them against gaining the knowledge of good and evil. Adam and Eve thought about this, but in the end decided knowing both good and evil like God did was preferable. God said, Okay, but this is what mankind will face for selecting this option. No fear, however, because I will be with my people to guide them in the way of salvation.
You see a punishing God, and I am not sure why. I see a God who is loving, even when his people go against his wisdom. He is there to guide people through the choices that have been made by themselves or by others that have an effect on their life. These are two very different philosophies.
