I think almost everyone understands that good intentions can lead to bad outcomes. But, also, everyone understands that good intentions can lead to good outcomes. Determining which is which is a very hard problem. One strategy might be, "Don't do anything unless I'm absolutely certain it will lead to a good outcome." If you do that, you'll miss out on many opportunities that would have good outcomes but who's certainty isn't up to your standards. So while the intention behind pointing out that good intentions can have bad outcomes is good, the outcome is bad.
