Who's to say that they didn't? Maybe that's why Kaworu acts like he's high when he first shows up at Nerv HQ.
Also, he was being drugged so that he wouldn't kill himself while in Seele's care.

24 does make it clear enough that Kaworu is more "in touch" than Rei is. The NGE2 game seems to indicate, however, that for all Kaworu knows, there may be an emotional disconnect. I.e., he does not really "feel" this whole "incarnation of Adam" thing and may even be afraid of it on some level. Much translating to do...
