Naraku was created when hundreds of demons fused with the thief Onigumo. Because Onigumo is a part of him, he finds that he still bears Onigumo's lust for Kikyo. The reason he turned Inuyasha and Kikyo against each other was because he wanted the Shikon Jewel. And only if it was tainted with darkness(caused by Kikyo's hatred of Inuyasha) would its evil aura be strong.
If ever there was a villain who wanted all the power, but never dirtied his own hands nor fought his fights for himself, Naraku takes the cake! In Japanese, his name literally means "depths of hell," and it matches him shockingly well. He manipulates demons and humans alike in order to achieve his goal of obtaining the complete Shikon Jewel. And in doing so he's caused an unimaginable amount of pain and suffering to practically all the other characters. He's responsible for tricking Inuyasha and Kikyo into betraying each other, the curse of the Wind Tunnel in Miroku's family, the death of Sango's family and using her brother Kohaku as a servant, trapping and killing Koga's comrades, and even tricking Sesshomaru into joining forces with him for a while. But he almost never performs any of his evil schemes himself. He often lays complex traps and uses others as pawns to do his bidding, or he creates demon incarnations of himself to control. But even one of his incarnations, Kagura, despises him because he has her heart, the key to her very life, and refuses to give it to her, so she's forced to follow his orders against her will.
It seems everyone has a reason to hate Naraku. But no matter how many of his plans Inuyasha and the others have foiled, nor how many times they think they've got him beat, he always has more death and suffering to cause. He's definitely one of the most cunning(and evil) villains of all.
