Exibit A, incredible. I know I'm wasting my time but let me correct you:
-Arthas was a cunt even before he picked the sword, he intentionally sabotaged his men so they wouldn't return home in Northrend.
-Arthas was never mind controlled, he actually actively pushed out Ner'zhul from the Helm so he could be in charge, everything fucked up that happened in Northrend? 100% Arthas.
-Arthas' soul was taken by Frostmourne but it never mind controlled him, it empowered him. If you condemn Sylvanas you will condemn Arthas, or even more so.
-Sylvanas' literal character is one of being a hero that defended her homeland to her last breath and didn't get to have a clean death. ''Arthas is a hero'' I guess that's why the Blood Elves still recall the fall of Sylvanas to this day because she isn't.
-Her literal being, her very soul was ripped to pieces by Arthas, she's not just a zombie, read what a Banshee is once, it'll do you a lot of good.
Arthas was a manchild before the sword, and he's a cunt even more so afterwards, that's why he's where he is. Sylvanas never had the choice, he made it for her, that's why she abhors the fucker. Basic lore right there.
