Am I supposed to feel bad for someone who obsesses over an airhead? Am I just heartless?
You are right, she is just plain retarded.
I think it's a fetish of a lot weebs being able to have your 'dumb doll' like Madoka in your rape dungeon. After days of starvation in the dungeon she would just drink your semen like she drinks milk.
Because Madoka helps Homura breathe easy.
Mami's the real airhead.
Anons as well as Urobuchi would love to try and convince you that you should, but no I don't think you should feel bad at all and you are certainly not heartless because of that.
In terms of rank of who I felt bad for, I felt bad for Sayaka, Mami, and Kyoko the most and Homura and Madoka the least.
