Whether injustice is a special virtue?

❌ Objection 1 : It would seem that injustice is not a special vice. For it is written (1 Jn. 3:4): "All sin is iniquity [*Vulg.: 'Whosoever committeth sin, committeth also iniquity; and sin is iniquity']." Now iniquity would seem to be the same as injustice, because justice is a kind of equality, so that injustice is apparently the same as inequality or iniquity. Therefore injustice is not a special sin.

❌ Objection 2 : Further, no special sin is contrary to all the virtues. But injustice is contrary to all the virtues: for as regards adultery it is opposed to chastity, as regards murder it is opposed to meekness, and in like manner as regards the other sins. Therefore injustice is not a special sin.

❌ Objection 3 : Further, injustice is opposed to justice which is in the will. But every sin is in the will, as Augustine declares (De Duabus Anim. x). Therefore injustice is not a special sin.
