Im a cannibal because I am an environmentalest, not because it tastes amazing.

If you harvest all but the organs they need to live you can still use them as blood bags for your Sanguophages and blood transfusions

And then add / remove peg legs to train medical.

I think you mean nonconsensual organ arbitrage.

You forgot the drugs. Drugs are worth so much more than organs. Which gets you access to more organs as your colony wealth spikes.
