Lord Of The Flies; why does jack want to hunt?

I think that Jack is so compelled to hunt because he feels that because he failed the first time that the boys encountered a pig. Meanwhile the others don't want to bother with the difficult task of hunting when they could just eat the fruit off of the pasture of bushes they found. Jack thinks that he lost face or failed by not being able to kill the pig on the first day. He may also want to earn the respect of the others by catching food for the rest of the boys, as he lost the vote to be chief.
