“We may stay here till we die.”
With that word the heat began to increase till it became a threatening weight and the lagoon attacked them with a blinding effulgence. (1.125)
When Piggy says the word "die," he seems to bring fear into the island. He and Ralph don't even know that anyone else is on the island yet—but it probably would have been better for them if they'd been alone.
Within the diamond haze of the beach something dark was fumbling along. Ralph saw it first, and watched until the intentness of his gaze drew all eyes that way. Then the creature stepped from mirage onto clear sand, and they saw that the darkness was not all shadow but mostly clothing. The creature was a party of boys […]. (1.184)
Ralph doesn't exactly seem afraid here, but maybe he should be: the boys choir appears out of the "mirage" as a man-beast. (Don't worry; he'll be afraid later.)
"Shut up," said Ralph absently. He lifted the conch. "Seems to me we ought to have a chief to decide things."
"A chief! A chief!"
"I ought to be chief," said Jack with simple arrogance, "because I'm chapter chorister and head boy. I can sing C sharp." (1.229-231)
Sure, bet that C sharp really comes in handy when you're trying to keep a group in order. Jack thinks he should have the power because he's always had it. There's nothing special about him; he doesn't have any particular talent for leading. He's just arrogant. And sometimes that's enough.
