Photographs of dead animals lied on a white paper in their position on the road. Indeed, these animals were killed by collision with a car, a bike, a truck...
Though, without true explanation, the forces (speed, inertia, resistance...) don't justify completely their death.
Are they legally dead and the collateral victims of our choice to drive ? Can we put these death in a perspective of chance or from an order ? How can we justify it ?
