I do love my characters!! But not in the way that Momma loves her babies or the way that I love my friends in real life; more in the way that like, God loves his creations. I do dearly love them, but I'm also their orchestrator.
Though, I definitely have favourites, and when my story's done you'll proooooobably be able to tell who they are. xD My favourites aren't necessarily the ones I'd get along with best or the ones I agree with (the opposite is often true), just the ones who are the most interesting to explore, to me, and so those characters do tend take bigger roles in the story.
I think it's cool to disagree with your characters, or to find that you wouldn't get along with them, like you described for yours! But I think it is bad to hate your characters. There's a really cool excerpt I recently grabbed from Slacktivist's Left Behind analysis that put it in a way that really clicked for me -- here's the most relevant piece:
To create is to love, but apparently not always. [The authors] do not love [this character]. They despise their creation. Their contempt for her and disgust with her is tangible in every scene she appears in.
I think the authors expect their readers to share in this contempt, but that's not how this works. When an artist creates a character that the artist does not love, readers or audience members don't come to dislike that character, they come to dislike the artist. It is the writer — or actor, or painter — who reveals himself as unlovely. The character just becomes an expression of that unloveliness.
"Love" here doesn't mean approval or agreement -- it's just, that you truly know and understand this character. In order to write a character well, I think you have to be able to empathise deeply even with a monster, even with a character you wouldn't "like" as a person, even with a character whose actions are despicable and inexcusable. You may not "love" them in the traditional sense, but.... if a creator hates their characters, I think it can hurt the honesty of their work.
