To whom ever it is, thats speaking of the dark triad, i say this. What you seek is a utopian land. There will always be a dark and light. Neither can exist without the other. Now, people can be conditioned to behave in certain ways, but then you have the genetic components to think of. A certain breed of dog can be trained to be aggressive, even with proper environmental conditions. Its called cellular memory. Dark triad people are the same. Or, a society could utilize this component and put them in possitions like, well, soldiers who kill the enemy. But the true question is, is state sanctioned murder murder? A serial killer gets the death penality, but the military sniper gets the medal. Is this your sense of morality? Kill all the dark hats and you simply turn into the very thing you hunted out of good.
Well, now i get the alexa crumb dropped last night.
