Why did voldemort want to kill harry

As a child, I always saw Voldemort as this evil character who would stop at nothing to murder Harry simply because he was, in fact, quite bad. However, now that I'm grown up and reread the books, it turns out there's more to him than that after all.It all began with a prophecy. The prophecy said that a boy born at the end of July would be able to defeat Voldemort. There were two boys who fit this description - Harry Potter and Neville Longbottom. The reason why Voldemort chose to go after Harry lies in the fact that both are half-bloods.When he tried to kill Harry, Voldemort was actually stealing his own life force. Isn't that wicked?

The prophecy that set Voldemort on this whole plot. A prophecy was the reason behind it all--- that a child born on that night in late July to parents who had (plets of ink wasted on this) defied Voldemort three times should be born with the power to bring him down. Harry and Neville were both born at that time. The Dark Lord chose Harry for various reasons, such as his being a half-blood too like himself. He thus marked him as an equal. An attempt was made to kill Harry when he was only an infant, but instead there came out his accidental equal-Voldemort somehow transferred a piece of his own soul into him and this meant that on a level with You-Know-Who (whether Harry liked this or not) was now Harry's unintentional Horcrux.

Voldemort wanted to kill Harry Potter because of a prophecy he'd heard. The prophecy, made by Sybill Trelawney, foretold that a child born at the end of July, whose parents had defied Voldemort three times and lived, would pose a threat to Voldemort's power. Harry was one of two children who fitted the description, the other being Neville Longbottom. However, Voldemort marked Harry as his equal by choosing him as his target, hence sealing his own fate. His aim remained to kill Harry throughout the series as he saw him as a constant threat and obstacle to his ultimate purpose of achieving immortality and complete power.

In Harry Potter, Voldemort wants to kill Harry because of a prophecy. The prophecy suggests that 'The one with the power to vanquish the Dark Lord approaches... Born of those who thrice defied him, born as the seventh month dies.' Both Harry Potter and Neville Longbottom appeared to be possible candidates, but Voldemort picked Harry, binding him as an equal with himself. That left a deep connection between the two of them and now Harry was no longer a simple opponent for Voldemort.
