I tried to read about the three groups play but I didn't exactly get what was the purpose of that. If punish had the highest points in game, everybody would try to punish in order to get maximum reward.
As far questions are concerned, I got punishment on almost all the wrong doings during my childhood because my Father was very strict. But with time when I grew up, I found that, punishment was not the solution and that had made me weaker, my morale was so low, self-esteem and self-confidence was almost zero or negative and I was like nothing in my own eyes. But now I'm mature and I'm definitely against punishing anybody because punishment only make the situation worse and it's not the solution. I'm eldest among my siblings but I never treat them in the way I was treated. :(
