The Enchiridion 93
93 Both the First and the Second Deaths are the Consequence of Sin. Punishment is Proportioned to Guilt PL 40, 275
And neither the first death, which takes place when the soul is compelled to leave the body, nor the second death, which takes place when the soul is not permitted to leave the suffering body, would have been inflicted on man had no one sinned. And, of course, the mildest punishment of all will fall upon those who have added no actual sin, to the original sin they brought with them; and as for the rest who have added such actual sins, the punishment of each will be the more tolerable in the next world, according as his iniquity has been less in this world.
Quorum damnatorum futura sit mitissima poena. Nec prima tamen qua suum corpus anima relinquere cogitur, nec secunda qua poenale corpus anima relinquere non permittitur, homini accidisset, si nemo peccasset. Mitissima sane omnium poena erit eorum qui praeter peccatum quod originale traxerunt, nullum insuper addiderunt: et in caeteris qui addiderunt, tanto quisque tolerabiliorem ibi habebit damnationem, quanto hic minorem habuit iniquitatem.
