Roadkill is a fact of life, but it's supposed to be animals, not people
Gotta agree with you, Silvio.
Anybody who values ducks above humans has wrong priorities. Two people are dead, due to criminal stupidity, as you put it. Her sentence reflects that, and sends a message to other drivers who may think they're being kind to animals when in fact their behaviour is highly dangerous to humans.
Same thing goes for reflexively swerving to avoid an animal . . . although those drivers often suffer a different penalty when their car hits the ditch, rolls over and they end up with massive injuries, or simply dead.
