David Cronenberg said this quote

“ As an artist you look into yourself to understand the human potential to be all kinds of things that are not necessarily pleasant but are real - a criminal, a murderer, a sadist, a rapist; to be all of these things that many people are. You can't allow yourself to say, 'I'm a different species from those people.' Because you aren't.The criminal as monster is kind of common. That's very convenient because you can then say, 'Of course I'm not a monster, therefore I'm not a criminal therefore I have no potential in tern of criminality.' And that lets you off the hook. That gives you a nice wall between yourself and them. ”
