[HitoriTomoyo]

Mami wasn't evil, she was misguided. A lonely person seeking friendship in the hell she unintentionally (somewhat) threw herself into and she just couldn't bear the loneliness when Madoka offered to be by her side.

I feel relieved that she did not end up being the decieving-type of character but her character as a whole is just one big tragedy. It's just so saddening.
