Analysis shows that he still inherited and will live no longer than 16 years, with a bunch of skin transplants and constant pain, as if he was burned alive - "no, we will not abort, we love him and so on."

But having the result in your hands, your own masha, sadistic self-loving creatures who love no fucking him in fact, but just love to tear down their mascha instincts.
Okay, hand like a wing, well down. Bad, but if this is the only chance under old age, maybe they will develop more or less, and surgical reconstruction will be done. But do they leave those who are born only for torment and death—well, you are sick evil creatures?
