1. Q- What if Jack and the other hunters never came back with a pig?
A- The bloodthirst and savagery in them would start later, and Jack might have never switched sides because he could have been working on the signal fire.
2. Q- What if Piggy was the one to switch sides because he was tired of Jack always torturing him.
A- it would different because there would probably less killing because I cant imagine Jack coming out and killing tons of people.
