Any community's arm of force - military, police, security - needs people in it who can do necessary evil, and yet not be made evil by it. To do only the necessary and no more. To constantly question the assumptions, to stop the slide into atrocity. - Lois McMaster Bujold
Toward the accomplishment of an aim, which in wantonness of atrocity would seem to partake of the insane, he will direct a cool judgement, sagacious and sound. These men are madmen, and of the most dangerous sort. - Herman Melville
Custom will reconcile people to any atrocity, and fashion will drive them to acquire any custom. - George Bernard Shaw
