Sylvanas was not killed, but rather captured. Barely clinging to life, Sylvanas Windrunner was brought before Arthas in his dark temple. She protested, saying she deserved a clean death, but Arthas, having had to fight her every step of the way, responded by telling her after what she had put him through the last thing he would give her was the peace of death. She was tortured, mutilated, and finally killed for Arthas' pleasure. He desecrated her spirit, corrupting her body and soul, and brought her back as a whirlwind of torment and hatred. Thus, Sylvanas Windrunner became the first of the high elven banshees. Sylvanas, now an undead banshee, was a complete and total slave of the Lich King. In her undeath, she aided Arthas in his assault against her own beloved Silvermoon in order to secure the legendary Sunwell for the Scourge.[6] Her mangled body was sealed in an iron coffin by Arthas, as a way to further torture the ranger.

Although her deeds were done for selfish reasons....she does have MORE then enough reason to do so, considering her past. Being brought up by a well known and respected family. Ranger-General of Silvermoon, and having all of that taken away because Arthas wanted to have a Banshee General? Yeah that would drive me mad too.
