Many different thinkers in Catholicism have proposed different theories regarding what original sin is compared to individual sin. From this, different theologians have thought that original sin incurs different punishment than individualistic sin.
I am reading St. Thomas Aquinas and it would seem to me that he believed original sin's punishment is an immediate loss of fullness, where 'human nature is left to itself, and deprived of original justice'. Does this punishment however equate to eternal damnation, or does eternal damnation follow as a consequential punishment to the fallen state of deprived justice? In other words, is the punishment of original sin equatable to death and subsequent orientations to sin and does specific punishment (being possibly eternal damnation, punishment in purgatory, etc) accorded to certain individuals, follow as a possible consequence if not prevented by grace?
Also, Aquinas notes the distinction between satisfactory punishment (punishment of a penitent nature serving the potential of merit) and penal punishment (punishment accorded legally to the individual to fulfill justice).
Would the punishment for original sin, if the previous suggestion that original sin's punishment is not an eternal damnation but rather only the 'loss of original justice', be of a satisfactory punishment nature (if such were to be possible through grace)? And if such is so, would the individual facing eternal damnation be of a penal punishment nature?
