I've been observing many patients now but all of them are mainly criminals in asylums. Although criminology is VERY interesting, I'm stumped in my overall impression on sadism and its role in murder. I know what it means, I know how it's used, but everyone is both a sadist and a mascohist, right? It's impossible not to be, but it possible not to know exactly which part plays the dominant role... but I don't know exactly what to make of sadism/masochism's role in psychopathy versus dementia...
