That's another explanation :-D Depending on how old the average dragon could become and how much Kilgharrah valued his own life and happiness.

I would even understand if Kilgharrah didn't care anymore, given that - except for Aithusa - his entire race had been wiped out. Would we want to live alone in a  world of dragons?

On the other hand, the whole fuss around the prophecy was quite a waste of energy then.
