He is or has been the largest advocate and instigator of a (one) medical philosophy of "the ends justify the means" in the U.S.A and beyond. He believes that old methodologies and ethics of hypothesis falsification and "first do no harm" respectively are holding back advances in treatment and prevention that could see improvements in outcomes orders of magnitude greater than what is available today.

It is a form of critical theory progressivism that runs afoul of accepted medical (and many private citizens, besides) ethics which itself rejects utilitarianism outright. An important note, however, is that many (perhaps the majority of under 40's), would agree with Fauci's ideas if asked cursorily.

Fauci is under the magnifying glass by such as Rand Paul because Fauci's -ideas- make it likely that his actions are wrong and/or evil and anecdotal evidence of his -actions- give weight to that concern.
