Why do people adore Blair Waldorf?

Firstly, I have to say I have nothing against her (she's one of my favourite characters because she is interesting), but apart from her fashion, dedication, and looks, I don't understand why.

I don't understand why people adore her so much, I mean, she does so many bad things throughout the show. Sure, at times she was a good friend (for example, when Serena killed a guy) but I think everyone forgets how bad she actually is when she wants to be. She is such a mean person to Jenny humphrey, even from the start of the show when Jenny was 14. During the sleepover episode, she literally dared Jenny to do such horrible things like steal from her mothers shop just to get in trouble with the cops.

During ivy week, sure, it was horrible that Serena slept with Nate, but she told everyone that Serena was an alcoholic without even confirming the story, and she ended up hurting Eric very badly.

When Blair found out she was about to get accepted at Yale and started to not care about her assignments (when she got a bad grade), she tricked her teacher into coming to a random abandoned area near the lake, just to go to the opera without the teacher.

And remember that time when Blair told the dean of Yale that Serena 'killed' a guy after acting like she was Serena's best friend (when Serena first told her)!!!!! I don't know, it's just insane to me how people could not hate her at times. She is an entertaining character, but not likeable.

I understand, at times Blair is a good friend and she "gets what she wants", but for no reason do I understand why she does not get as much hate as Jenny Humphrey, Chuck, or Serena. It does not make sense to me. Idk, thoughts??
