Some say that by the mere ability to resist evil we become the very evil we fight. That view equates initiation of aggression for spite or profit with defense of self and family.

Failure to plan or failure to act when necessary is not noble, merely irresponsible for it leads to extinction and encourages predators to victimize others besides us.
