Law 42
Trouble can often be traced to a single strong individual – the stirrer, the arrogant underling, the poisoner of goodwill. If you allow such people room to operate, others will succumb to their influence. Do not wait for the troubles they cause to multiply, do not try to negotiate with them – they are irredeemable. Neutralize their influence by isolating or banishing them. Strike at the source of the trouble and the sheep will scatter. –Robert Greene, The 48 Laws of Power (review)
Zechariah 13:7b
Strike the Shepherd that the sheep may be scattered
