To sum upIllidans behavior has less to do with tyrande and more to do with the fact that he has a huge ass ego and Malfurion keeps unintentionally showing him up. Illidan always felt that he was the better twin, his chosen school of magic was superior to his brothers skill and chosen school of magic. Illidan always thinks he knows better than everyone else and he is willing to do anything to get the result he is looking for no matter how many people tell him that it is morally bankrupt, the ends justify the means. He loves his brother but damn people need to recognize Illidan’s greatness first. Tyrande was just a trophy wife that he lost to Malfurion even though Illidan considered it a sure thing, she should of swooned as soon as illidan told her, “Tyrande, I choose you! Aren’t you lucky?!?”
Illidan is a dick.
