No Purgatory after Final Judgment?

[Wesrock]

Purgatory is a purgation of attachment to sin. This will happen for all who are saved, even for those alive at the End. It may be done in the twinkling of an eye, but everyone saved is purged of attachment to sin before the beatific vision, in this life or after. There won’t be anyone left in need of it after the final judgment.

 

[Benadam]

I kinda think that the final suffering will cause purgatory to come down to earth, that is, for the faithful. This will cause mass conversions. Once everything gets set in stone, the twinkling of an eye change will happen.

Those in Hell are there forever. That is in Scripture and it is an infallible teaching of the Church.
Obviously then Hell is not destroyed.
