> But, from a medical ethics point of view that's not beneficial to them at all, why should they care if some one night stand they never saw again dies of cancer? This is a very subtle but misleading rephrasing of what you should have said instead, which is: "But, from a medical ethics point of view that's marginally beneficial to them at the risk of inducing potential harm". The four pillars of medical ethics are Autonomy, Beneficence, Non-Maleficence, and Justice. Your phrasing effectively subtly side-stepped the third pillar as irrelevant, when presumably it was the one factor whose influence led to the delay you mention.
