He's not evil, just insane.
When the 3 of them ran into cenarious, he didnt like the druid way at all. Prefering the arcane magics. He was practically a mage in the beginning. He had golden eyes as well, the High borne and the elven culture at the time believed golden eyes mean a great fate was in store for that person.
But it actually meant great druidic potential. Illidan could have studied half as hard as Furian [who didnt have the gold eyes] and been many times more powerful a druid. But he didnt. he was more of a mage at first.
Other than the eyes, Furion was his identical twin, the reason they looked so different later is because of the paths they took in life. Tyrande chose Furion because,
Quote:
"Raw power is no substitute for true strength, Illidan. That is why I chose your brother over you."
Now the thing is, he has done things which were horribly evil, but he had a good side to him. But all that he did that was good, had the core foundation of his addiction and desire for magic and power. He had grown up with expectations of greatness from everyone and wanted to show them his true worth and his great power. In the process of doing so he ended up seeking power as an ends unto itself. he was addicted to it, desired it beyond all else [except maybe Tyrande, in his entire lifetime, pretty all his actions were either based on seeking power or seeking her]
he was originally with the highborne and the legion, his burning eyes and the spectral sight it gave him were a gift, reward and a taste of power from Sargaras hismelf. If all had gone as planned. Azhara, the queen of the highborne [the nobles of the nightelves who had access to the well of eternity] would have been Queen of the Legion, and Illidan one of his generals, Archimonde and Kil'jeadons peer.
Ofcourse he later fought against the legion with Furion and Tyrande.
he then creates a new well of eternity after the last one blew up the entire center of the continent [all the water between the 2 continents was once land and it all formed one continent]. Hundreds of millions of mortals of different races had given thier lives, much too many great heroes, gods, dragons, eternals and ancients had died defeating the legion...and he goes and recreates a new source of the very thing which has caused all of it in the first place, raw arcane magic.
Arcane magic is naturally currupting, unstable and addictive. Elunes influence saved the nightelves from this till Azhara and her ilk strayed.
The highborne were arrogant nobles, those who were rich and talented in arcane magic and thus they saw themselves as superior and kept the well of eternity to themselves. During this time the rest forsaked arcane magics and kept to their worship of Elune. Druidism eventually came to them when Cenarious revealed himself to Illidan, Furion and Tyrande. The highborne and the "lower castes" were phsyically different at this point due to the paths they had chosen and followed for centuries of passing generations, despite the fact they were the same race. They eventually gave into their lust for power and worshipped Sargaras. His legion was brought to the world and started to slaughter everyone who wasnt highborne.
later on, he consumed the skull of guldan, out of good will to save the lands and kill tichiondrous but also at the core of his motivation to consume it, was his desire for power and addiction to magic.
Kiljaedon contacts him after he's exiled for what he became by consuming the skulls magics. and asks him to destroy the lich king, who he says would wipe out all life on azeroth...plus Kiljaedon will reward him with power too.
later on he recruits the naga some how and slaughters many coastal night villages and destroys their boats so Maiev wouldnt follow him to the tomb of sargaras.
When he gets the Eye of Sargeres and uses it to kill the lich king...by making the artifact cause earthquakes to make the entire continent of northrend to collapse into itself. This accidently releases an old god locked up in northrend, and on a more positive/negative note, indirectly results in the creation of the Forsaken.
Now this sorta seems nice, and it sorta seems stupid that Furion stopped Illidan and destroyed the eye. But well...its sorta obvious that destroying an entire continent would lead to DIRE ramifications for the entire planet.
He saves Tyrande later on alongside Furion. The last good thing he'd ever manage to do.
He did at first, save outland from the legions presence. he never intended to enslave the broken but simply recruited.
In his direct assault against Arthas when he travels to Northrend, he and Arthas eventually face off rind outside the entrance to the frozen throne. Arthas is heavily empowered by being so close to the lich king [whose directing all his power into Arthas]. When warriors who are peers fight, eventually one of them has to fall. and in this fight, Illidan fell.
This broke his mind. never before had he actually FAILED in direct combat. Blizz revealed he had seen Arthas ascend and transform into the lich king. Brought to outland by keal and vashj.
When he came back he realised he needed a mightier army to stop kil'jaedon punishing him for his failure. He recruited the remaining demons who previously served the burning legion [quite a good offer, their continued survival and a promise of great power vs death at the hands of the person who defeated their leader, the mighty magtheridon]. He recruited the remaining crazed orcs from the old horde, by promising them glory and power through the blood of magtheridon.
His own mind was gone at this point. The person we knew before northrend didnt exist anymore. He enslaved the broken at this point, they would have had nothing to do with the fel orcs who had mutated them from the proud dreanai they once were, not to mention kill 80% of the dreanai population but at that point they longer had a choice in the matter.
When the races of Azeroth poured in, due to the dark portal being reopened. No one knows what Illidan declared war on the naaru and shatarath without provocation, instead of joining them. Possibly keal'thas, who was secretly working with kil'jeadon, had a role to play. it was his main army afterall who had marched up to shatar to fight them [though it ended up they joined the naaru as the scryers, knowing what their fate would be if they stayed with keal].
and also, in illidans crazed mind, the mighty naaru were beings of purity of light, they were another powerful force IN HIS LAND. He was lord and master of Outland. The shatar would never bend to his will and he would not stand for an independant group of such powerful beings to exist in his land. He was capable and powerful enough already by himself to defeat the legion alone [or so he may have thought], he didnt need anyone else.
