I hate Hayley for following things:
•No remorse•
Hayley never showed remorse for killing a human when Hayley was just 13!
(I just found out she's often compared to Teen Wolf character Malia Tate but I have to say Malia shows remorse for killing her adoptive family).
•the whole thing with Tyler•
I just have no words. Hayley manipulated him, 12 hybrids, even Caroline and Klaus and we all know what had happened. How on the Earth Klaus never wanted to punish her for using him as a pawn in her game? She murdered 12 hybrids and indirectly Carol Lockwood and showed later no remorse.
•her attidute towards Sophie•
Hayley had no problem with murdering 12 hybrids but when others wanted to use her she was like ‘i'm the victim’. When she said ‘i will kill you’ (in 1x06 if I remember correctly) to Sophie I really wanted to punch Hayley so so much.
•killing witches•
Just because Esther wanted Hope dead Hayley murdered a lot of New Orleans witches simply because they were the same species as Esther. So following Hayley's logic Siphoners and witch-vampire hybrids should hate every witch in the World for the actions of the witches from the Gemini Coven– if others would have been following this logic then Nora and Bonnie shouldn't've been friends simply because Nora was a hybrid with siphoning power (something that the GC witches saw as an abomination) and Bonnie is a witch (the same species as members of the Gemini Coven).
•the whole ninth ward coven massacre•
I know it was Davina who asked Hayley to do the killing but Hayley still agreeded to do that. She murdered even more witches who did nothing bad to her or her daughter Hope. Ironically this act later had a huge part in the downfall of the Mikaelson family because when the Ancestors led by Kara destroyed Davina's soul Marcel and Vincent wanted revange.
•taking Hope from Klaus•
She took Hope from Klaus thinking her precious werewolf pack could protect her better that the Mikaelsons.. she temporary lived in junkyard with a child!
•killing the Strix•
She was murdering the Strix as a revange for Jackson's death. But she completly ignored the fact that the actual killer Tristan had already been punished.
•werewolf nobility•
She told Elijah that she didn't like being a hybrid because she lost the purity and nobility of being a werewolf. Was she so noble and pure when she was a werewolf? Didn't she murder 12 hybrids for a flash drive?
I'm sorry for a long comment.
