Wouldn’t it be worth investigating why they are executed? Given this organ trade is going on I wouldn’t be surprised if their “justice” system is being literally trigger-happy because they benefit from the resulting organs being made available.
Executed in a systen where law is not supposed to be impartial but only a tool among many to upkeep the states power. I don't think humans where worth much after death before modern organ transplantation. State arbiter gets more reasons to less leniency when there is a profit to be had from the execution.
In an already 'unfair' system adding profit motive to executions can only worsen the humanitarian result.
It’s a whole other thing of killing the patient on purpose to harvest their organs.
