Uh, I'm pretty sure you're wrong. Nico had to explain the Doors of Death to everyone else. They hadn't heard of it before at all, and if Thanatos only lets out the nice spirits (which seems like it would be very much against the rules) then why would Percy's first thought be that Carter is and evil spirit who came through? He doesn't need the curse of Achilles to survive that punch because he is in water, which heals him and gives him strength. He's also probably a lot harder to kill than a mortal, even without the Achilles heel.
