Humanity must die because men are fragments of Lorkhan. If they make it so that Lorkhan does not exist he will have never existed (because Metaphysics work like that in TES) and thus reality would never have been created and Elves would get to be mindless globs of selfless goo, which the Thalmor thinks would be really really neat.
Talos is a fragment of Lorkhan that looked so much like Lorkhan that a bunch of other fragments of Lorkhan saw him and were all "Lorkhan!" and globbed onto him making him one big-huge Lorkhan fragment. They can't kill him by conventional means, so they've got to convince everyone that he's not that much like Lorkhan so that all the little globs of Lorkhan on him go "Wait, you're just some guy!" and drop off him, and indeed he will be just a guy, because everybody thinks he is.
It's a bit more complicated than that, but that's the gist of it.
