Yes, lets defend the guy who wanted to use High elves as human shields.
They used the New Blight to fight the Scourge. Even after Wrathgate.
If Sylvanas was pure evil, she could have just used the original Blight: It only kills the living & the forsaken are immune to it, making it the perfect weapon for an undead megalomaniac.
Anytime I engage with Arthas stans it feels like explaining the basic events of the game to a child.
