Yes you are right Macalaure and I know that, what I was suggesting was, did the One Ring once in the posession of Isildur give added power to the curse. The word spoken in anger, coming to fruition. The word IF in the sentence suggests that if Sauron had not been defeated, then the Men of the Mountains would have died quite normally, why not just say: You let us down therefore you're cursed whoever wins. When did this curse start to take effect anyway, did they all die very quickly or did the Army of the Dead get a new recruit every so often until they all died, if so what about their children and their childrens children, was this army getting bigger by the day?

You are also right I think about Isildur not having the power to do this thing under normal circumstances, where did the power to invoke this curse come from, I do not believe it was from Eru, yet I would admit that he permitted it, and at the time only he would know why.
