Don Quixote and Lady Macbeth

From Stephen King's Firestarter:

Andy moved slowly away from the van.  The other fellow . . . had his gun out now.  He pointed it at Andy.  He was less than fifty feet away.  "I advise you very sincerely not to move," he said in a low voice.  "This is a Colt forty-five and it makes a giant hole."

The young guy with his wife and baby at the picnic table got up.  He was wearing rimless glasses and he looked severe.  "What exactly is going on here?" he asked in the carrying, enunciated tones of a college instructor.

The man with Charlie turned toward him.  The muzzle of his gun floated slightly away from her so that the young man could see it.  "Government business," he said.  "Stay right where you are; everything is fine."

The young man's wife grabbed his arm and pulled him down.

Query: Between the young guy and the wife, who is being practical and who is being romantic?  Who is being reasonable and who is being irrational?  Who is really trying to save lives and who is merely pretending?
