I think execution is absolutely wrong and never morally justifiable. However I don’t see why execution + organ harvesting is worse than execution alone.
Any effort to stop executions now includes the fact that potential donors recipients will die.
Even with the opt-out donation model of some European countries they usually have surprisingly short waiting lists for most organs, as unfortunately plenty of accidental deaths occur every day.
An inmate's death sentence can be commuted to as less as 12 years after this process. https://zh.wikipedia.org/wiki/%E5%AD%99%E5%B0%8F%E6%9E%9C
At the same time they are sexualizing and grooming kids.
It creates a motivation to find the innocent guilty.
Never underestimate how absolutely low someone will go to make a buck.
Unless of course he is a DONOR.
