Yes, and that’s why now she’s giving anduin choice, to try to force him into abandonning hope, and make him feel exactly same just like she did when she got killed by Arthas? To make him feel the same feeling of failing your people and making them die?
The literal exact same thing she did with Delaryn?
Yes, let’s just complete ignore the fact that Sylvanas is the most impulsive, spiteful, overly emotional character in the whole universe, because it would suit your argument.
You can cover your ears, close your eyes and scream, but this is just what Blizzard is doing. They made her this evil, sorry being that can’t deal with her own emotions, so she passes the pain on other people, even if it means wiping almost their whole race in the proccess.
There’s no other reason for Sylvanas to try to make Anduin abandon hope than Blizzard showing us she’s still the same Sylvanas that started war of thorns. The same sorry being who spreads pain to feel better about herself.
