Voldemort
Voldemort craved the Wizarding world, it symbolised acceptance, somewhere he belonged where no one would reject him because he wasn't the cute baby or the cheery cheeky child. He wasn't the smart one with potential to be a genius. They all learned of course, all the children and even the staff of the orphanage.
They could never prove anything but they all knew it was him and it gave him power. But potential parents could sense this power and it seemed to make them reject him. All he wanted was to be accepted and belong but none of them wanted him and this was imprinted on his young mind.
And then Dumbledore arrived. He was introduced to the Wizarding world, to Hogwarts and to Slytherin house.
He thought it was there in Slytherin house that he would finally be accepted but he was wrong. It was filled with people that once again rejected him, but this time it was all because of something that he had no control over, his blood was not pure.
Once again the students of Slytherin house, just like the children of the orphanage, soon learned that if they would not accept him then they would be put under his power. And so Voldemort was born.
His fall into Dark magic was fueled by a desire to find a way to make people accept him, desire to be with him, to belong to him so that he could be the one in control of the decision on who was rejected.
Soon though he began to meet resistance from the 'Light' wizards and the war began, eventually he was declared the Dark Lord and then the prophecy was made.
Voldemort knew he needed to get rid of this prophesied one and quickly, nothing was to be allowed to challenge him, not now that he finally had everything that he wanted. Through fear he had acceptance, through power he had control and he was not going to give any of it up.
What had begun as a craving, quickly turned into an obsession and now it was an addiction, he did not see this; Voldemort only knew that there was nothing that would make him give up what he now had no matter what the consequences were.
Voldemort didn't Hate the Wizarding world, no he Loved it.
Dumbledore thought Voldemort was incapable of Love, because of this he thought the 'power he knew not' was Love, but he was wrong because Voldemort was more than capable of Love.
He Loved the Wizarding world, he Loved being accepted, he Loved Power.
The fates knew this; they knew it was not Love that could defeat him.
