Jack's descent into madness??

Quotes for Jack: 1. ‘Jack had him by the hair and was brandishing his knife… The chant rose ritually, as at the last moment of a dance or a hunt. ‘Kill the pig! Cut his throat! Kill the Pig! Bash him in!’ 2. ‘Which is better - to be a pack of painted Indians like you are, or to be sensible like Ralph is?’ ‘Which is better, law and rescue, or hunting and breaking things up?’ 3. [After smashing the conch] Suddenly Jack bounded out from the tribe and began screaming wildly. ‘See? See? That’s what you’ll get! I meant that! There isn’t a tribe for you anymore.’
