Because some roads you shouldn't go down. Maps used to say "there be dragons here". Now they don't. But that don't mean the dragons ain't there.
- Billy Bob Thornton as the hitman, Fargo episode 1
Those kids chose the wrong road to go down. And they ran into the wrong dragon to annoy. I hate defending anyone so cold blooded, but this is all on those two dummies. They deliberately chose the wrong thing to do, met someone a lot worse than they were, and paid a horrible price for their bad decision making. Leave Byron Smith alone to his own devices and in a few years he dies unnoticed and the cops go into his house and marvel at his collection of weapons and stockpiled ammunition. Raise his ire and end up in the morgue.
Sorry, but I just can't feel sorry for criminals, not when their own choices lead them to a bad end. They failed at being good citizens of a society long before they encountered Byron Smith.
