For the first time, I disagree. Her design is one of my favorites of the show, and even though she acted in her own interests at the expense of others and didn't play by the rules, I forgive her under the circumstance that she was just a little reckless and immature that showed her capacity to make mistakes, which I find interesting in her as a character. Sorry about that, just felt like sharing.
I might agree with you had I not experienced many people like her in my everyday life. It makes it even worse to see it first hand. As a character she's fine, but in general I want to slap people like her and tell them to start giving some fucks about others. Ah well. Win some, lose some.
