Ok I agree but, like children when they do something bad… do they say sorry because they are really sorry of because they fear getting into trouble? Same thing applies here… And I would have to say that being a sinner myself I would admit that I fall and fail for many reasons and some of my intentions are imperfect and I am working on them, as we all should.
Part of perfect contrition is the resolution not to sin again. If you are not truely sorry… you are saying that you don’t have the intention to do it again. Imperfect contrition does not equal forgiveness. It is a prompting by the Holy Spirit to futher our look at sin and to eventually come to a perfect contrition.
From the Catechism taken from the Vatican website:
With special attention to ccc 1453:
1451 Among the penitent’s acts contrition occupies first place. Contrition is "sorrow of the soul and detestation for the sin committed, together with the resolution not to sin again."50
1452 When it arises from a love by which God is loved above all else, contrition is called “perfect” (contrition of charity). Such contrition remits venial sins; it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible.51
1453 The contrition called “imperfect” (or “attrition”) is also a gift of God, a prompting of the Holy Spirit. It is born of the consideration of sin’s ugliness or the fear of eternal damnation and the other penalties threatening the sinner (contrition of fear). Such a stirring of conscience can initiate an interior process which, under the prompting of grace, will be brought to completion by sacramental absolution. By itself however, imperfect contrition cannot obtain the forgiveness of grave sins, but it disposes one to obtain forgiveness in the sacrament of Penance.52
