Dalamar went to Nuitari because "Nuitari made no promises so he broke none." he already saw what Paladine allowed the highlords to do to his people. he saw many of his people die with Paladine's name on their lips, but did they get saved? he scorns the gods of good because he thinks they use the Silvanesti like game pieces on a board. even if he had been allowed to study white magic, he would have gone to black soon.
