One of the most amazing things about this scene is that it illustrates the character’s evil by showing an act of mercy that makes no sense whatsoever.
Think about it. You’ve killed a sheriff’s deputy and then a motorist, whose car you are now driving on the way to a $2m job that you know will involve killing more people. In the absolute middle of nowhere, a gas station attendant makes a point of telling you they’ve seen you, seen your vehicle, seen the direction you came from and speculate where you are going.
If you are that guy, you would kill the attendant without ado. You would be out of your mind to let him live.
Not this fucking weirdo, though.
