Sam at the hospital saw the old man and watched one person being taken up
Sam had already seen the light come for him on the street that night
The old man mentions The Other Ones
When Willie dies Sam sees The Other Ones drag him screaming to Hell
As this is the man who killed him Sam knows its deserved though seeing it is chilling
With Carl he did not mean for Sam to die, he sent Willy to steal the book
Sam still remembered Carl as his friend despite Carl choosing the wrong path
So we see that sympathy as he knows what coming and then as he watches it
