I tink Castiel's personality is his personality. From what Naomi said, I think that Castiel was different form the others since he kept showing signs of free will whenever she tried to remove his memories, and put him back to 'base zero'.

I think Naomi's group was the ones who tried to reset Castiel and Anna, before the archangels died, but after, Naomi tried to take control. Castiel was crazy when he was in 'God Mode', so he wouldn't have been able to look into his head.
