NORMAN It's too late for me. And besides... who'd look after her? She'd be alone up here, the fire would go out... damp and cold, like a grave. When you love someone, you don't do that to them, even if you hate them. Oh, I don't hate her. I hate... what she's become. I hate... the illness.
Norman Bates from 'Psycho' dir. Alfred Hitchcock.
