A crash had happened that no one meant to happen, and that was a tragedy.

And then a living man, unhurt enough to think and to act, had looked at his unconscious brother and chosen his own escape over his brother’s rescue, and that was a crime, and no confusion of the wreckage can blur the line between the two.

People sometimes want to soften it by pointing to the chaos of the moment, the shock, the smoke, the panic.

But the swap was not panic.
