Sylvanas sees her own people as tools to keep herself alive. She spreads the curse of undeath knowing it damns the souls of the afflicted. Under her regime, humans have been put into forced labor camps and experimented on. Despite not needing land to feed her people, she has commanded a campaign over nearby nations and used weapons of mass destruction that not only kill people but taint the land. And, despite all her talk about free will, she saw no problem in enslaving Eyir for her own needs.
Sylvanas is a typical dictator that will fake kindness towards others as long as they are doing what she wants. People are tools to her, she will respect them only so long as they are useful. At some point, her vengeance was all that mattered, now, she's worried only about her own survival.
She's also an hypocrite that laments her own cursed existence while killing and damning others to the same fate.
She's just cunning enough to hide her true intentions and manipulate others into her schemes, and that's it.
At some point, however, her plans and schemes will unravel, and she'll meet retribution. She's gonna he hoisted by her own petard.
