Sort of. Basically I think that the average necron doesn't have enough of a consciousness TO go insane. Not enough of them survived the transfer for there to be enough of a personality where insanity is an option. Lords and immortals on the other hand have more intact personalities and thus are more capable of going insane.
Do standard necrons have a programme? I thought they just did what they were told in a very instinctual sort of way.

. By the way Hellebore, thanks for reminding Xisor about the whole conciousness (or sentience maybe?) losing thing with the Necrons. I was afraid I'd have to give a lecture about the ware and tear of copying memory over a protracted period of time, which would cause you all to abandon the thread
