Adam didnt follow anybody...he made up his own mind to sin and disobey God...
He was the one who received the direct instructions from God not to eat the fruit of the tree of the knowledge of good and evil...Eve was not created at that time...

Oh come now... Adam and Eve were both forbidden to partake of the fruit from the Tree of Knowledge. Eve was beguiled by that ole serpent and partook of the fruit followed by Adam making the decision to do the same which resulted in Adam, when asked by God as to why they were clothed, promptly threw Eve under the bus and getting them both ejected from Eden. Sin had to happen in order for Jesus Christ to sacrifice himself to save US from certain death.
