Am I the only one who feels bad for Sketch?

Despite the bad things she did, I couldn't help but feel terrible for her.
I imagine that her obsession with Maxxie started out as just a crush, but because of her immense loneliness, it grew into a dangerous obsession. Think about it, she had no dad, no friends, and because of her mothers disability, she had to take care of her, meaning she had no one to be raised by - She seemed very much a lost soul, struggling through life, and longing for acceptance and content.

I especially like the fact that even though she used Anwar, she'd eventually grow to care for him and desire a genuine friendship - To the point that I was even saddened by the fact that that didn't happen.
I would have liked a better ending for her, personally.
