Whether everyone that sins through habit, sins through certain malice?

❌ Objection 1 : It would seem that not every one who sins through habit, sins through certain malice. Because sin committed through certain malice, seems to be most grievous. Now it happens sometimes that a man commits a slight sin through habit, as when he utters an idle word. Therefore sin committed from habit is not always committed through certain malice.

❌ Objection 2 : Further, "Acts proceeding from habits are like the acts by which those habits were formed" (Ethic. ii, 1,2). But the acts which precede a vicious habit are not committed through certain malice. Therefore the sins that arise from habit are not committed through certain malice.

❌ Objection 3 : Further, when a man commits a sin through certain malice, he is glad after having done it, according to Prov. 2:14: "Who are glad when they have done evil, and rejoice in most wicked things": and this, because it is pleasant to obtain what we desire, and to do those actions which are connatural to us by reason of habit. But those who sin through habit, are sorrowful after committing a sin: because "bad men," i.e. those who have a vicious habit, "are full of remorse" (Ethic. ix, 4). Therefore sins that arise from habit are not committed through certain malice.
