If you look at all the villains of World of Warcraft, you will notice that most of them were trying to do the good thing in a bad way. Some villains in WoW turned bad by someone else, while some are just evil. Most villains in WoW started out as good people but some events changed them. They were trying to save their people, in their own way. However, they took the wrong path and thus ended up becoming villains.
Let us start with Illidan Stormrage, the twin brother of Malfurion Stormrage. All Illidan ever wanted was to be appreciated and loved by Tyrande. If we look back at the events of War of the Ancients and Warcraft 3, you will clearly see how much he cares Tyrande. After the events of War of the Ancients, Illidan wanted to bring the Night Elves back to their old glorious status by creating a new Well of Eternity. However, all the other Night Elves, especially his brother and Tyrande were horrified at his actions. Thus, he was sentenced to spend 10,000 years in a lightless prison. Even when Illidan is trying to claim the Skull of Gul’dan, all he wanted to do was save his people by defeating Arthas. Sadly, he was unable to defeating Arthas, so he ran to Outland. Since his people had already disowned him, Illidan become a villain in WoW.
Kael’thas Sunstrider was once a senior member of Kirin Tor and the Price of Quel’Thalas. After the fall of Quel’Thalas, all Kael’thas wanted was to help his people with their arcane addiction by providing them with a new source of magic. Doing so, he allied himself with Illidan and the Burning Legion, once his people found this out, they branded him a traitor. Therefore, He became an outcast and a villain.
Arthas Menethil was the Crown Price of Lordaeron and a knight of the Silver Hand. Uther trained him as a paladin. Arthas wanted to rid his lands of the Scourge, but he took a darker path by taking up cursed runeblade Frostmourne. After that, he was lead by the voice of Lich King in his head. He ended up killing his own Father as well as his mentor Uther. Finally when Arthas took up the helm of dominator and merged himself with the Lich King, he became one of the most dominant villain of WoW.
Neltharion the Earth-Warder
Neltharion the Earth-Warder, now known as Deathwing the Destroyer was once a Dragon Aspect and the leader of black dragon flight. Thousands of years ago, the Titans gave him dominion over the earth and the places of Azeroth. However, the Old Gods who were imprisoned deep inside Azeroth drove him mad and he turned against the other Aspects. Thus he became Neltharion became Deathwing a villain of WoW.
Garrosh Hellscream the Son of Grom Hellscream, the former chieftain of the Warsong clan, and the former Warchief of the Horde wanted to see the Horde rise to their former glory he had heard about while growing up. Ever since Thrall invited Garrosh to join the Horde, he has been fighting and leading the Horde troops as seen in Northrend. Later he became the Warchief of the Horde but his hatred for the Alliance and the power of being the Warchief corrupted him as he used the Heart of Y’Shaarj and ruined the Vale of Eternal Blossoms. Thus, Garrosh became a villain in WoW.
There are others noble villains in WoW as well, like Malygos the former Aspect of blue dragon flight who went mad by thinking only dragons are fit to use magic, Sartharion the boss in Obsidian Sanctum is only there to protect the twilight eggs. Even Sargeras, the biggest baddest villain of WoW was once a noble Titan.
If we look at all the main villains of WoW we will see that most of them were good people. Makes you wonder, will Blizzard do the same thing in the next expansion of WoW, will we see another noble character turn into a villain in Warlords of Draenor. Who knows, maybe we see Grom Hellscream turn into a villain in the next expansion of World of Warcraft.
