Injustice

Injustice is a special vice for it opposes the specialvirtue of justice. It has, however, the aspect of a general viceinasmuch as every vice strikes against the common good whichjustice serves.

A person may do an unjust thing-from ignorance,perhaps, or passion-without having the habit or vice ofinjustice. But to do what is unjust intentionally and by fullchoice is the mark of an unjust man, a man with the vice ofinjustice.

Injustice is found only in what is suffered againstone’s will.

In its general essential kind, or *genus,*injustice is a grave sin. In small matters, however, it is a venialsin; slight acts are not in essential conflict with the good, andwith the fixed will, of the one who undergoes their effect orendures them.
