If I may ask, What do you consider to be “perfect contrition”? I think it might be helpful to the conversation if we knew how you see or define perfect and imperfect contrition.
The Catholic Encyclopedia defines perfect and imperfect contrition as:
Catholic teaching distinguishes a twofold hatred of sin; one, perfect contrition, rises from the love of God Who has been grievously offended; the other, imperfect contrition, arises principally from some other motives, such as loss of heaven, fear of hell, the heinousness of sin, etc. (Council of Trent, Sess. XIV, ch. iv de Contritione).
Does this fit with how you are defining perfect and imperfect contrition?
