Why does Jack commit toward Piggy?

Answer 1

If you are asking "Why did Jack hit Piggy?" The answer is that Jack was elated from having just successfully hunted a pig for the first time. He felt on top of the world, he felt that he had proved his skill and ability before his hunters. Then his self congratulations had been brought tumbling about his ears when Ralph told all the boys that they missed the opportunity of being rescued because the fire had been allowed to go out. This was a direct result of Jack 'needing' the two boys who should have been on fire duty to join his hunt. While Jack could grudgingly accept criticism from Ralph, who was bigger than himself and also the elected leader, when Piggy also spoke out against him it was a step to much. Jack could not accept losing face before his hunters by allowing a fat and unpopular boy to verbally chastise him without response. So, Jack punched him. Piggy was an easy target who was unlikely to fight back and who was unlikely to attract too much support. Jack was therefore able to unleash his anger and also the frustration he felt towards Ralph but which he was unable to express in that direction.
