I was thinking that apart from being able to defend yourself, cruelty and sadism might paradoxically be signs that an individual is, or at least was, in extreme attunement to the most intimate parts of the human condition and that's why he can be an effective sadist, because he understands. I remember a quote from somebody saying that only someone who understands people on a deeply profound level could possibly be a sadist. And isn't understanding people the same as understanding life? Wouldn't that make sadism a symptom of enlightenment? In our upside down world there are upside down people, who do upside down things, in an upside down manner, to at the end get back at this upside down society. And isn't enlightenment, in the same way, an upside down manifestation of what society wants?
