Hit the 5 on the runway. Because the farmer om the runway is doing nothing wrong hes chilling but the 5 farmers on the runway shouldn't be there and so the blame is on them.
This, even though if we're really gonna crash, a field is preferred to a runway since it is softer and has more means of dissipating energy. Sometimes you have to be brave and make sscrifices to punish the guilty.
What? According to the screenshot, there's one farmer in the field, and five on the runway. Or, at least, one near a field and five near a runway, but it definitely doesn't say there are five farmers in a field.
Even if the plane can steer and choose to hit either of the two "groups", they have to be physically near one another. The runway must be right at the field, which implies it being a route the farmers take to get to their fields.
It is ethical for someone to act in their own self-interest. With that in, the ethical choice is to pick the runway. Gotta get a higher score,
And you usually have a better chance using a runway, even during a crash
