How bout just learn to adapt the traits of "charm, confidence, ruthlessness, coolness under pressure" sans psychosis.
Screw psychosis- it's unpredicable and can be dangerous- and we shouldn't glorify mental illness (not stigmatize it) but we should be realistic and call it what it is.
It takes courage to grow up and become who you really are. ~e.e. cummings
We need the hard rough men patrolling our borders so we can sleep safe and sound in our beds at night.
This. Natural selection selects for the gene for antisocial personality, and research has shown that a proportion of every society will be made up of these types. But as a significant minority, or society would crumble from within. They are the ones who wouldn't think twice to put themselves at the front line of a tribal war. No hesitation, no fear, thirsty.
How this is manifested, makes or breaks a "psychopath" (clinical term, antisocial personality disorder). I remember in clinical psychology classes, reading that these people need a greater thrill/stimulation (of the "dangerous" kind) to feel what we would feel with much less extreme stimulation. Those brought up in a positive, functional environment grow up to be involved in work that is still aligned with society's values - like stuntmen, etc.
Those not, become ruthless killers, the parasites of our society.
So, just because someone is predisposed to this does not excuse it. Naturalistic fallacy. Environmental influences has a lot to do with how that will manifest. A big hint is if, as a kid, he is diagnosed with conduct disorder. (Yes, I used he as this is disproportionately skewed by gender)
Ps- it has nothing to do with MBTI personality type.
There's literature showing correlations between various MBTI dimensions and psychological disorders, so your statement is trivially false. It absolutely has something to do with MBTI personality types.
