Surgeon Plans To 'Reawaken' Cryogenically Frozen Brains, Transplant Them Into Someone Else's Skull (nationalpost.com) 125
Sergio Canavero, the Italian surgeon who plans to perform the world's first human head transplant within the next year, says he is preparing to reawaken cryogenically frozen brains and transplant them into someone else's skull. "In an interview with a German-language magazine, Canavero says he will attempt to bring the first brains frozen in liquid nitrogen at an Arizona-based cryogenics bank back to life 'not in 100 years,' but three years at the latest," reports National Post. From the report: Transplanting a brain only -- and not an entire head -- gets around formidable rejection issues, Canavero said, since there will be no need to reconnect and stitch up severed vessels, nerves, tendons and muscles as there is when a new head is fused onto a brain-dead donor body. Canavero allows that one "problematic" issue with brain transplants, however, would be that "no aspect of your original external body remains the same." "Your head is no longer there, your brain is transplanted into an entirely different skull," he told OOOM magazine, published by the same company that handles the Italian brain surgeon's public relations. The flamboyant neuroscientist who some ethicists have decried as "nuts" rattled the transplant world when he first outlined his plans for a human head transplant two years ago in the journal, Surgical Neurology International. Bioethicist Arthur Caplan called Canavero's latest proposal to merge head transplants with "resurrecting" the frozen dead beyond ridiculous. "People have their own doubts about whether anything can be salvaged from these frozen heads or bodies because of the damage freezing does," said Caplan, head of ethics at NYU Langone Medical Centre in New York City. "Then saying that he has some technique for making this happen, that has never been demonstrated in frozen animals, is absurd."

No, it's not that hard. In the off chance this quack succeeds in reviving someone, the chances are high that there will be substantial tissue damage.
The patient may experience unbearable pain, and being paralyzed, may not be able to tell anyone, so it essentially becomes torture.
When freezing someone, you end their suffering, so that's much more ethical than inducing more suffering.

Partially true. Slowly freezing tissues dosent damage them significantly, this we can do fairly well already. The hard bit is thawing them rapidly and uniformly to avoid cellular damage.
