Draigo is like the special boy whose drawing you put on the fridge. Yea, good job Draigo.
This of course is the real answer. Taking him to the warp denies him any actions of consequence in reality, and also denies him the glory of dying for the Emperor and Imperium.Why defeat him, when you can have him locked away in the Warp, having him slaughter endless Daemons - They are eternal anyway? This way he makes absolutely ZERO difference, as opposed to being dead where he could become a martyr.
Seems to me like they want him to think that he's immortal, yet trapped; A much greater punishment and mockery than just killing him.
He would still perceive himself as himself, and the warp domains as physical representations of their gods' personalities. I imagine it would be the same for daemon princes, due to the fact that their minds are originally mortal.You dont mean physically do you? Since he'a just a clump of emotion up/down there if I'm not mistaken.
