What may be for others doenst apply for others?

If 2 people commit the same sin, is it possible that one might believe that its a mortal sin while the other is believes it is a venial sin?

Does consciousness play a role?

The answer is clear when one understands the 3 conditions of Mortal Sin: 1) Grave Matter, 2) Full Knowledge, 3) willful consent…Grave Matter may apply to both, but full knowledge and willful consent might not.

If the person who commits a grave sin, but put no thought to it when they do it, are they still guilty of mortal sin?

If they previously knew that such a sin was of grave matter but went ahead and committed it anyway then that is a mortal sin.



Consider something which most people agree is a very bad thing: adultery.

One person commits adultery and realizes what a terrible and serious thing he has done.

The other just blows it off as no big deal.

The difference actually lies in their consciences.

One has a conscience which still works well; the second has a conscience which has been dulled by poor teaching or repeated sin or by other factors.

To the extent to which the latter person is responsible for his condition of ignorance, he is culpable of that sin, despite “not knowing” that it was bad.

It depends on why he put no thought into it. No time to think and he just had to react quickly? Sudden situation? Ignorance? Just doesn’t care about God or goodness or anything?
