From my reading (and I will admit I do not see the logical reasoning at all, which I think is why the case was later overturned) the judge thought that they were guilty not of failing to predict it, but of giving an inadequate message. Presumably, to me this implies some sort of laziness, or intent to not make more of an effort despite knowing better.
I will admit that I am biased being a doctor dealing with this daily, but I think that blaming this solely on the pharmaceutical companies is easier to do than looking at what is happening to our culture, expectations of pain, the way we deliver healthcare, how we grade healthcare (for example read about Press Ganey's Fifth Vital Sign).
I agree that there is a problem with over prescription of opioids, but this problem isn't solely due to a simple conspiracy of drug makers. I think that sort of rhetoric is unhelpful.
