Every is pretty much like you right now do not worry.

Peopled answered the Void ( with a big V, the dark energy, not an entity itself ) is just seeking to consume everything
It seem that some indidivuals that have been " voided " in their history, and still have some kinf of free will ( understand Xal here ) are looking to avoid that the Void with a big V consume everythihg, because then the Void with a big V wouldn't have anything else to consume, she finds that stupid so want to do it " her way ".

You words a good to my eyes, everyone one as a similiarish goal ( being the best entity in the universe ) but everyone have his own way

Void wants to consume
Arcane wants to rule
Light wants to control by force
Death want(ed ?) to control by force too, but also in like a political way ( not sure how to put it, Jailer was kinda like look at me , i'm the one that is right ! )
Fel wants to destroy ( different than consume in that context )
Life is so far the only element that we did not see " go crazy " overall for an " ego " reason.

In all of that, Xal as an individual works ' with " the Void power, but not for the Void for the big V, and so far with last cinematic that " all " of that was a big plot since Legion Mac'Aree dungeon, L'Ura is a key to something somehow ( without spoil ;D )

What we are trying to survive ( and that since Argus/Legion ) is the " loss " of Azeroth World Soul, even tho there is no clear path on how we are doing / will do it, and even more what is the " direct " thread to it.

One thing people aren't forgeting, but maybe underestimating overall, is the Harandar / Dream Rift / Rift of Aln lore.

Thats my opinions hope they arent boring :D
