I'm reminded of the king of the Swamp Castle from Monty Python and the Holy Grail: "Let's not bicker and argue about who killed who." It should not need saying that if millions of deaths are the result of a simple, easily avoidable mistake (or gross negligence) then that is kind of a big deal. The Titanic led to better lifeboat regulations. We need to understand our role in the origin of this disease even if only so that we can learn our lesson, whatever that may be.
