Whether a circumstance aggravates a sin?

Objections

Objection 1 : It would seem that a circumstance does not aggravate a sin. Because sin takes its gravity from its species. Now a circumstance does not specify a sin, for it is an accident thereof. Therefore the gravity of a sin is not taken from a circumstance.
Objection 2 : Further, a circumstance is either evil or not: if it is evil, it causes, of itself, a species of evil; and if it is not evil, it cannot make a thing worse. Therefore a circumstance nowise aggravates a sin.
Objection 3 : Further, the malice of a sin is derived from its turning away (from God). But circumstances affect sin on the part of the object to which it turns. Therefore they do not add to the sin's malice.
