Exactly. Akin quoted Francis’ Amoris document which referred to 1735 and 2352 of the CCC which talk about this diminished or nullified culpability.
Elsewhere, Card. Ratzinger once spoke about homosexuals not being in a state of mortal sin, because of their “objectively disordered condition.”
I have asked priests and a bishop about 1735 and have not received an answer AT ALL (it is fair to say). There’s two questions really, which of our particular sins fall under 1735 – I suppose anything that the CCC says is “grave matter”; 1735 stops short of answering the question about confession, but if it didn’t mean that, then why did it publish 1735 in the first place?; and then, what are the “other” conditions which diminish or nullify one’s responsibility?
Note that in 1735, inadvertence is only one of the conditions; the other conditions must refer to willful sins.
It appears then, that 1735 and 2352 (or 2350) apply when the Pope and some bishop says they apply – maybe. That’s merely the appearance of things when I see 1735 actually referred to, which is seldom. (I have brought this up many times in these forums.)
I would note that NO priest has ever questioned me in the confessional, about whether I met any of the conditions of 1735 for any of my sins.
No matter how I personally quibble about 1735 and responsibility for sin, I know scripture says, “God is not mocked, stop sinning.”
