What success does Jack have and how does it lead to further tension between Jack and Ralph?

Jack and the hunters return from the hunt covered in paint and humming a bizarre war chant. Ralph sees that the hunt has finally been successful: they are carrying a dead pig on a stick. Nevertheless, Ralph admonishes them for letting the fire go out. Jack, however, is overjoyed by the kill and ignores Ralph. Piggy begins to cry at their lost opportunity, and he also blames Jack. The two argue, and finally Jack punches Piggy in the stomach. Piggy's glasses fly off, and one of the lenses breaks on the rocks. Jack eventually does apologize about the fire, but Ralph resents Jack's misbehavior. Jack considers not letting Piggy have any meat, but he orders everyone to eat. Maurice pretends to be a pig, and the hunters circle around him, dancing and singing, "Kill the pig. Cut her throat. Bash her in." Ralph vows to call an assembly.
