Hindsight may have the benefit of 20/20 vision, but in real life the capacity to act is often greatest when the clarity to see is worse.
Conversely, by the time everything is crystal clear, freedom to act may be heavily constrained.
Adolph Hitler, for example, could easily have been stopped in his tracks early in his career; it was not until he could only be stopped at enormous cost that people knew beyond doubt why he needed to be stopped at any cost.
