That is a reasonable answer I suppose. The concept of vigilante action has, i believe, been close to the surface of most cultures. The behaviour of those who try to force someone they believe to be "evil" out of their community would, obviously, be accepted by the vigilantes. In a broader sense though, can such behaviours be seen as an extension of the greater good defense. That is, can such actions be acceptable if there is a society wide belief that no other alternatives are available to supposidly protect a local community?
