Defense of ones self or of ones family is more than a right, it is an obligation and a duty owed to the gift of life.
"There exists a law, not written down anywhere, but inborn in our hearts; a law which comes to us not by training or custom or reading but by derivation and absorption and adoption from nature itself; a law which has come to us not from theory but from practice, not by instruction but by natural intuition. I refer to the law which lays it down that, if our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right. When weapons reduce them to silence, the laws no longer expect one to await their pronouncements. For people who decide to wait for these will have to wait for justice, too, and meanwhile they must suffer injustice first. Indeed, even the wisdom of the law itself, by a sort of tacit implication, permits self-defence, because it does not actually forbid men to kill; what it does, instead, is to forbid thebearing of a weapon with the intention to kill. When, therefore, an inquiry passes beyond the mere question of the weapon and starts to consider the motive, a man who has used arms in self-defence is not regarded as haveing carried them with a homicidal aim."
"Civilized people are taught by logic, barbarians by necessity, communities by tradition; and the lesson is inculcated even in wild beasts by nature itself. They learn that they have to defend their own bodies and persons and lives from violence of any and every kind by all the means within their power."..................................Marcus Tullius Cicero, during the final years of the Roman Republic
