It’s one thing to harvest organs if the patient dies of accidents/natural causes, and personally I am in favour of the opt-out system.

It’s a whole other thing of killing the patient on purpose to harvest their organs.

At least several thousand people are executed in China annually. Can their bodies be used?

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.
