Honestly, I think "harvested" is worse than "stolen". You "steal" from another person, you "harvest" a resource that has no humanity.

On the contrary. Harvesting organs is terrifying.

Just add one more word... harvesting Human organs, and the alliteration sends a shiver down you spine.

"Stolen" is so much nicer than "murdered."

Is it? In the context of people's organs they're both pretty abhorrent.
