Yeah, I heard the same. That would have been totally cool. I totally would have done several playthroughs with that.

Anyway, he went crazy because of the proximity to the heart, because of Corprus... the very Corprus he wants to spread. Corprus makes people mad, and Dagoth Ur is no different. That last dwarf and the Nerevarine are the only exceptions. But even if you were right, and it's the constant betrayals and exclusion he faces that made him mad, it still would make no difference. Either way, he is a threat that needs to be stopped. Hence a sympathetic villain maybe, but a villain nonetheless.

Also, the Nerevarine is not literally Nerevar, or at least might not consider him/herself so, so the "best friend" part is a bit shaky...
