Because he was going to give a portion of his liver (not kidney) to his sister anyways before she was told she would be able to receive a full liver transplant.

If his sister had gone in alone without a donor, or if they had said something like "thank God, they found you a liver in time!" without mentioning he was going to give her a portion of his, no one would know about their previous intentions (certainly not MC). but MC was trying to save another patient's life - who apparently didn't need a full liver transplant - as a portion could work for her too. Due to the liver's unique ability to regenerate, the partial livers of both the donor and recipient soon grow into complete organs. And it wasn't like they were going to give his sister only half the liver and save the other half for the original patient.

Yes, it's fiction. It wouldn't happen in real life. But they're trying to give us "hope" in the story. Would you want another death in the story?
