Aiden died because the sword he was stabbed with was an Oni-sword, and it was poisoned and slowed his healing down, add to that the fact that his wound was lethal, and to the fact that when Void-stiles died, Aiden was already "killed to death" so his Wolfpowers couldn't heal him fast enough, even after poison supposedly left his body with Nogitsune-stiles gone.. I mean, it was just BAD timing for him, and so he died. =)

(Plus the actor wanted off if I am not mistaken?) same with Crystal, she wanted out. and made it so her character died off. leaving no possibility to come back other then as a possible memory of something we have yet seen. (she got too old)
