So in war3 FT when Sylvanas minds control or kill all the livings to become the biggest power on Lordaeron that was being good?
When Arthas purge Stratholme, becomes corrupted by the Lich King, destroy Lordaeron, raise Sylvanas as undead, bring the legion and fuse with the LichKing those were good deeds?
Being the hero does not mean being a good guy in warcraft.
