I. Respect for Human Life

From The Catechism of the Catholic Church

2265
Legitimate defense can be not only a right but a grave duty for someone
responsible for another’s life. Preserving the common good requires rendering
the unjust aggressor unable to inflict harm. To this end, those holding
legitimate authority have the right to repel by armed force aggressors against
the civil community entrusted to their charge.⁶⁶
