Why not decompose the carcass if you're doing this for ecological reasons? Encouraging consumption just makes it seem like a cruel not-solution for the poverty problems in this state.
One deer is enough meat for a whole family for many months.
I have literally, no joke, come around a bend to find two deer fighting in the middle of the road at 10:30pm. I see fresh roadkill (as in: wasn't there yesterday) pretty often on my drive to work in the mornings.
Unless, it's somehow sanitary or safe to eat raw meat that was also left outside for the same amount of time, so long as you cook it thoroughly after.
Logistically, I don't get how roadkill could be fit for human consumption unless immediately bagged and stored.
