Whether venial sin can be forgiven without Penance?

Objections

Objection 1 : It would seem that venial sin can be forgiven without penance. For, as stated above (Question [84], Article [10], ad 4), it is essential to true penance that man should not only sorrow for his past sins, but also that he should purpose to avoid them for the future. Now venial sins are forgiven without any such purpose, for it is certain that man cannot lead the present life without committing venial sins. Therefore venial sins can be forgiven without penance.
Objection 2 : Further, there is no penance without actual displeasure at one's sins. But venial sins can be taken away without any actual displeasure at them, as would be the case if a man were to be killed in his sleep, for Christ's sake, since he would go to heaven at once, which would not happen if his venial sins remained. Therefore venial sins can be forgiven without penance.
Objection 3 : Further, venial sins are contrary to the fervor of charity, as stated in the SS, Question [24], Article [10]. Now one contrary is removed by another. Therefore forgiveness of venial sins is caused by the fervor of charity, which may be without actual displeasure at venial sin.
