In our country we have always upheld the right for one to defend themselves and their family and property. The Left has promoted violence but attempted to eliminate honest American citizens from defending themselves.
Today the jury exonerated Kyle Rittenhouse of murder and upheld the right to bear arms and to defend ones self against agression and bodily harm.
The Catechism of the Catholic Church, basing itself on Scripture and Tradition and the constant teaching of the Church, expounds on this right and even duty of the individual.
CCC 2263 The legitimate defense of persons and societies is not an exception to the prohibition against the murder of the innocent that constitutes intentional killing. “The act of self-defense can have a double effect: the preservation of one’s own life; and the killing of the aggressor.… The one is intended, the other is not.”
CCC 2264 Love toward oneself remains a fundamental principle of morality. Therefore it is legitimate to insist on respect for one’s own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow:
“If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful.… Nor is it necessary for salvation that a man omit the act of moderate self-defense to avoid killing the other man, since one is bound to take more care of one’s own life than of another’s.” (St. Thomas Aquinas, STh II–II, 64, 7, corp. art.)
CCC 2265 Legitimate defense can be not only a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm. For this reason, those who legitimately hold authority also have the right to use arms to repel aggressors against the civil community entrusted to their responsibility. (2240)
