Because Snape hates him! or at least it seems that way. There are many examples of Snape going out of his way to make things hard on Harry, he subtley makes fun of him and his friends (the worst one, in my opinion, was when Hermione's teeth gets cursed to grow 10 times their normal size and when Snape is notified says "I don't know, she looks the same to me.") , and he takes points from griffindore for seemingly no reason-- I would hate him too! Another reason is that his father had a long going rivalry with Snape when they were in school together, though rivalry may not be the right word. James was popular, Snape wasnt and was often picked on by James. Harry finds out about this in the 5th book but still cant seem to trust Snape.
James Potter humiliated Snape when they were at school and Harry look exactly like his father. Harry is also a constant reminder that the woman he loved, Lily (Evans) Potter, choose James over him.
His chief foe is Lord Voldemort, the most evil wizard to date. Voldemort was a half-blood orphan who began life as Tom Riddle. His mother died when he was born, and he never knew who his Muggle father was until much later. Other enemies of Harry's are the Muggle relatives who raised him. They are the Dursleys -- Vernon, Petunia (who is Harry's aunt) and their fat son Dudley. They hate and later fear Harry because he is an "unnatural freak", a wizard. At Hogwarts, Harry's main enemy is Draco Malfoy, son of Death Eater Lucius Malfoy.
Because they hate each other (as in Draco and Harry) or that person is their accomplice (as in in the Death Eaters) or maybe they're just British.
Yes!Absolutely! She was as evil as James was to Snape when they were young, times 10! Oh, she kicked Dumbledore out of school, sacked Trelawney, made another scar on Harry, and made detentions for doing studying too long! She was very evil. I hate her.
Yes. In Harry Potter and the Half Blood Prince, Bill is bitten by Fenrir Greyback, a VERY,VERY,VERY vicious werewolf. Before the full moon, he positions himself near children. He bites them young, to get them 2 hate wizards.[he bit werewolf remus lupin.]Bill won't end up as a full,official werewolf,because he shook fenrir greyback off, and madam pomfrey acts FAST.
The Dursleys did not treat Harry as their own son because they hated that he was a wizard, Vernon because he was a bigot Petunia because she was jealous, and Dudley because he was raised to treat Harry badly.
Not really. Harry Potter hated Severus Snape until after his death when his true nature was revealed.
No, in fact, both of them hate each other.
Yes, Severus Snape stood for everything James Potter hated and he was also the best friend of the person James' loved.
Voldemort and his Death Eaters. He used to hate Severus Snape before discovering he was on the good side. He used to hate the Malfoy's before they changed sides and before Narcissa saved his life.
Yes because Snape thought of Harry as the weakest student of the class
Because Gryffindor and Slytherin are rivals and Snape did not like Sirius' friend, James Potter. Also, Sirius and James targeted Severus as someone to humiliate throughout their school years.
Yes, and he never tried to disguise that. But he loved Lily Evans/Potter.
No, they hate each-other very much.
James ( Harryโs father) made fun of him at school and James stole Lily (Harryโs mother) from Snape who loved very much
He is a hateful evil bully, who willingly joined Voldemort.
SPOILERS Snape is mean (to Harry) as he hated harr'y dad and harry look's just like him but on the other side of harry family tree , snape loved lily and was secretly portect him and he ends up diying to save his ture love's only son. also he just don't like other people sometimes and hate gryffindors anyway
He either hated or disliked his uncle, aunt, and cousin, because of the way they treated him. Many of the other people he hated or disliked were from Slytherin House, including Draco Malfoy, Severus Snape, and Voldemort himself. Then there was also Dolores Umbridge - I am not sure from what house she was.
