What made it worse was that literally a few episodes earlier Ten had implied that life as a Cyberman was a living death, yet apparently existance as a paving slab is tickerty boo...I guess it isn't that different from being the face of Boe!
To be fair, he did see how Humanity evolved and that the last living human (nevermind all those humans running around when the Master is at the end of the universe) was nothing but a stretched face. Maybe he assumes that's a suitable way of living for humans. Afterall, if they do it of their own free will, it can't be all that bad.
Personally, I think RTD just has some fucked up fetishes.
