Well, as the Doctor said, they need genius. And they might believe the assimilation process might remove any anti-Dalek "impurities" that the Daleks might think to have.

Asylum was an amazing episode and I found it more than sad when the big Oswin reveal came through. "Eggs-ter-minate. :P" Which also makes me wonder how they'll get Oswin back into stage in Ep6.
