If this is the case then Nozdormu goes insane long after killing himself. His younger selves will kill Infinite Nozdormu and then after the years and years the younger self who killed him grows old and loses his mind.. Starting the circle all over again.

I think this ‘facing himself’ scenario fits perfectly. Aman’thul showed Nozdormu when and how he will die to prevent him from abusing his power. But if you showed someone when and who was going to kill them, wouldn’t that make them even more inclined to avoid their fate? He would use his power to get rid of his perpetrator, right?

Well, what if what he saw was himself killing… himself? How could be possibly prevent that?

So here’s how it goes down. Centuries pass. Nozdormu is nearing the end of his ropes. He goes mad despite knowing this is exactly how it’s going to end. Since he can’t just go back and kill himself, he sends his Infinite Dragonflight (Bronze dragons in the future) to randomly alter time trying to completely shift Azeroth’s time line to save himself. This explains why the Infinite Dragonflight aren’t just targeting a specific being.

Our present day Nozdormu travels into the future to face his future counterpart, knowing this is what he must do from what Aman’thul showed him.
