And Frank's never killed an innocent because he always goes into things knowing what he's gonna do. He doesn't fight in the streets with rocket launchers and he doesn't fight guys with particle rifles, he fights them with normal guns and does so in areas without any innocent bystanders, usually within the confines of the enemies' lair.
I'm sort of offened how you seem to be implying how people who enjoy the comic are enacting perveted revenge fantasies, like we masturbate over the book to the gore.
