You missed the point. We can and always choose the wrong course in our lives. We can and never choose the right way. While Protestants accept that Christ is our atonement and the perfector of our faith, Catholics feel there is a need to work one’s way. Thus the purpose of purgatory. Of course Mary would have been excluded.
Would you say that Judas could be in purgatory?
Catholics do not accept the doctrine of total depravity. While we are wounded by Original Sin, with the grace of baptism we need not be defeated by it. We only lose when we surrender to it.
"Catholics feel there is a need to work one’s way. Thus the purpose of purgatory.
Purgatory is not a place. It is a timeless state named for the purgation of our sins to ensure that we are pure when we enter heaven.
"Would you say that Judas could be in purgatory?"
Since I cannot say with any certainty or knowledge where Judas is or is not I cannot comment except to sat that it is a possibility.
