//I think Tyrael’s fear of the nephalem is unfounded, at least as far as the demon hunter class goes. He worries about the nephalem being tempted by the dark and succumbing to it, and going on to destroy heaven, hell, and Sanctuary. But the demon hunter already deals with this; they have dealt with this dilemma of either resisting the dark or succumbing to it since the day their village was destroyed. This is shown explicitly through the contrast and usage of their hatred and discipline. They have resisted using their hatred for negative goals up to now, especially with the help of their discipline, and have shown themselves to be staunchly on the side of good. This is made even more explicit by the demon hunter’s statement that her to-be peers and mentors saw the strength to resist the demons in her already, even before she was taken on as a demon hunter. She has also resisted Valdraxxis, Prime Evil Diablo (the demon hunter specifically states that she is the only one who can resist his corruption, and she wins), and Malthael in their attempts to break her. Ergo, she will not be tempted to the dark. So, if any of the classes should be the least of Tyrael’s worries, it’s the demon hunter.
