It depends. I blame the dentist that fixed my tooth in a substandard way and then I had to have it removed, because the bad fix had it broken a couple of years down the line.

I also blame him because, over the years, other patients of him had trouble for his sloppy work.

I absolutely praise the dentist I went after that one, who made his best to fix everything, explained me the pros and cons of every decision he made, and ultimately got me top notch (as best as could be done).

Sorry for he weird "counterpoint", but the example could be open to ambiguity. I still get the point: don't blame the guy fixing things when it's someone elses responsibility.

In my case: I'd be wrong to blame the 2nd dentist for the mistakes of the 1st.

Sure, I just wanted to say that the criticized behavior of blaming the problem on the person that is trying to solve it is something that also happen to doctor. Simply to say that it is not a prerogative of programming or safety.

Sure, and in retrospective my answer was a bit more to gp than to you.
