Sylvanas's end game is to destroy the people who brought us, the war of the ancients, the scourge, the dark portal, etc. It is genuinely too bad the Dwarves and Gnomes chose to join the baddie faction, but Humanity, Eradar, and Kaldori are responsible for every major crisis.

By that very logic though, her own people (the Forsaken) are the descendants of humanity, and her past people (Quel'dorei) are close cousins to the Kal'dorei. I don't buy that she's out for destruction purely for the sake of destruction either, she's more complex than that
