Civilization acts only to focus the energy of mankind into works for the collective good. It does not change his true nature.
We can, and should, observe civilization, respect it even, but we should never abandon the human animal. It is what drives us. It is what makes us understand others.
We must appear, in all things as gentleman, but should a man push us off that path, we must make him regret that push more than any regret he has ever held in the entirety of his life. We must make him an example for all time that we are not to be trifled with. That the penalty for any attack will be severe. We must reveal our true selves.
There's a time to be a Gentleman, and there's a time to be a Savage.
