Adam, Eve, and the Unfollowed Instruction

Today in class, we read 1-3 In the book of Genesis. We were asked to answer just one question: who was to blame? Within the first three parts of the book of Genesis, God is creating the world and mankind. He creates animals, day, night, water (oceans) the sky, etc. The most important thing God created within those 3 parts was man kind. He created Adam, the first man. After creating Adam and further developing the world, he felt that Adam needed a suitable helper. After not being able to find one, he created Eve out of one of Adams rib. After having put Adam up as ruler of everything on the ground, he then gives Adam and Eve one specific instruction, not to eat from the tree in the center of the Garden of Eden. "You are free to eat from any tree in the garden; but you must not eat from the tree of good and evil, for when you eat of it you will surely die." These are the specific instructions God told Adam. Now let me ask you this, would u ever disobey gods instructions? Can you guess what happened? Yes, Adam and Eve were convinced to eat from the tree. This is what eventually got them kicked out of the garden of Eden. Now, who's to blame? Adam for not enforcing the one rule God gave them? The serpent, for convincing Eve to eat from the tree? Or Eve, for eating from the tree when she was specifically told not to. I believe that it was a mix of both Adam and Eve's fault. Adam should have been there to make sure everyone followed the directions, and Eve should have just listened to her one specific rule.
