Danger is not a moral judgement, but a rational one. Iranian nuclear scientists weren't assassinated for no reason, and I highly doubt anyone involved had serious moral accusation to make against them. The U.S. also banned export of cryptography in the past (and still does in some cases), solely based on strategic grounds, not because mathematicians are "bad people". People in positions of or close to power and/or possessing certain knowledge are dangerous, not because they are necessarily morally repugnant, but because of their privilege and ability.
