Nothing could have been done better.
At any point in time do you think someone made a decision... yes we could do it the best way... but we'd rather try this instead.
At all times all decisions have been made with the best intentions, therefore, it did not "go wrong" what we have today is the best possible scenario.
Sure, looking back other decisions could have had a better outcome however at the time of a decision, it was the best one available.
Not sure if I'm making much sense here but at least I know what I mean
