If Saxon is the Brain Surgeon and he killed Cassie and try to frame Zach for it, then he definitely does not follow the same code as Dexter. Dexter will eliminate Saxon and Vogel in the next few episodes. Not before either Deb or Hanna are killed by either Saxon or Vogel (probably Deb), Grief stricken Dexter will retire from the MPD and move to Argentina with Hannah.
