OF MURDER
(In Eight Articles)
In due sequence we must consider the vices opposed to commutative
justice. We must consider (1) those sins that are committed in
relation to involuntary commutations; (2) those that are committed
with regard to voluntary commutations. Sins are committed in relation
to involuntary commutations by doing an injury to one's neighbor
against his will: and this can be done in two ways, namely by deed or
by word. By deed when one's neighbor is injured either in his own
person, or in a person connected with him, or in his possessions.
We must therefore consider these points in due order, and in the
first place we shall consider murder whereby a man inflicts the
greatest injury on his neighbor. Under this head there are eight
points of inquiry:
(1) Whether it is a sin to kill dumb animals or even plants?
(2) Whether it is lawful to kill a sinner?
(3) Whether this is lawful to a private individual, or to a public
person only?
(4) Whether this is lawful to a cleric?
(5) Whether it is lawful to kill oneself?
(6) Whether it is lawful to kill a just man?
(7) Whether it is lawful to kill a man in self-defense?
(8) Whether accidental homicide is a mortal sin?
