Jimm, if the 'donation' is done knowingly whether as a financial transaction or with the idea of helping another humna being, it's a different story altogether. Here, prima facie, it seems that Dr. Amit duped these patients and removed their kidneys without their consent. He seems to have used persuasive means only avail. to a Dr. to remove their kidneys. That is definitely unethical, immoral, and downright criminal.
