One: That was actually addressed in-story: "Something Interesting" included preventing people from dying and otherwise being hurt. The same applies to suicides and so on.
Two: Surgeries are usually performed inside, in rooms without windows. Even because these rooms have to be sanitized and so on.
Three: Most forms have fully functional hands and feet. And, again, "interesting" does not include "having flights fall".
And yes, even if there WERE deaths from it (and the wish itself, based on what Jon would consider to be interesting, prevented that from happening), it would STILL be less harmful than a coup d'etat.
