and why do we need hard and fast rule. I guess If you are observing the process you could tell if many hands are helping or destroying.

Analysing cases on an individual basis might be improved upon by predicting when such things become prevalent. There may be during a long history of observing processes that one can tell that such and such is a recipe for help or not based on certain conditions that have been present in the historical cases.
Planning to prevent is better then monitoring/checking
Cure is better than treatment
If it is possible that certain traits are necessary in the scenarios where destruction is going to occur then a different hat can be worn for those situations and likewise in situations where the opposite is going to occur then a different mindset accordingly again.

Asking people to leave after getting them started is bad for their morale. Not getting enough resources before we start the task might look like bad planning. If there is no hard and fast rule that is one matter, but if there are hidden rules than can be discovered then they should be found and utilised.
