Harry Potter and the Deathly Hallows question

Harry Potter. I'm sorry, but he is arrogant, needs to sort out his temper and is generally just a bad character overall. I don't really have a specific reason as to why I don't like him, but I guess it's just the character.

Peter petigrew. He is so selfish and trades Harry’s parents life for his own. He is cowardly and he framed Sirius. Evil. I also don’t like Harry much as his temper is so easy to activate.

Id have to say Hermione, although most of the time shes not that bad I just find she has a lot of insufferable qualities. The whole house elf thing was a bit much and snide and/or know it all comments she makes get a bit annoying in my opinion
