I would legitimately be worried if they were doctors, but they're philosophers (in medical ethics). Their job is to come up with insane moral edge cases and then try to follow them to their logical conclusion - the siller and more unhinged the better. This is absolutely expected of them.

Many of their other papers have a similar flavour:

  - How do we justify research into enhanced warfighters?
  - Compulsory moral bioenhancement should be covert
  - Abolishing morality in biomedical ethics
