 Some have responded that the poor man’s inability to give voluntary consent to trial participation stems from injustice, not natural disease, and that this makes a big difference. But surely medical aid that saves consenting victims from the horrible results of injustice and carries unpleasant side effects can remain fully permissible. For example, following the 2010 earthquake in Haiti, it was fully permissible for the U.S. military and its physicians to perform consensual life-saving leg amputations. It was permissible whether earthquake injuries were purely natural, partly the result of non-U.S. injustice (local contractors’ independent neglect of safety rules), or partly the result of U.S.-perpetrated injustice (long-standing U.S. meddling in Haitian politics at the expense of accountability, including accountability for neglectful construction projects).
