I should be studying for Physics right now

I saw Sin City again on Sunday. Very odd people were sitting around us.
End of Movie:
Hartigan: *kills himself*
lady sitting next to me: OH SHIT!
I don't know why she was freaked out by this when she was laughing everytime someone was killed/maimed/castrated. Speaking of Sin City here is a feminazi rant about it. She really missed the point of some of the scenes.
