Yeah I've found that too. Nobody's perfect , but there is such a thing as a "scarey character flaw". Warm blooded rage can be unpleasant.But a "cold rage" where someone starts defending it all brazenly , is a bit spooky..
I think there's probably more *psychological* psychopaths than physically violent ones nowadays. What do they call em , "social psychos"? I actually wonder , how many of em go that way because they were bullied as kids. Those people can often be spooky..
