Harry PotterEditHarry Potter was Voldemort's arch nemesis and tried to doanything to kill him. Just for Voldemort to kill himself. He even tried Legillimency on him in the Ministry of Magic in 1995. Harry finished Voldemort off on 2 May 1998 in The Battle of Hogwarts while in Priori Incantatem. Voldemort never knew what Love was so he never forgave Harry Potter for what he did in 1981, 1995 or 1998.
