I think we all got suckered on Adam's purpose plotwise. I haven't seen anyone saying they figured it out before Zachariah explained it, at least. If Michael could possess John despite his being only half right, surely Michael could possess Adam despite his being probably about a quarter right--whatever makes John acceptable and Dean ideal might be like the Y chromosome, so John and Dean and Sam and Adam are guaranteed to share it, and Dean and Sam have a double portion because Azazel has to have gone for Mary because she's a potential-if-not-ideal Lucifer vessel.
