If you not believe in purgatory so you believe Jesus went to hell and preached to demons.
Hell is the very absence of God. So Jesus is not God?
The verdict of the two judgements is equal.
The difference being one particular and another public, with Christ presence. And after that the souls will be reunited with the bodies (maximizing the verdict).
There's no second chance after death. Your destiny is eternally fixed. Purgatory is not a second chance. We have infinite opportunities to repent while on earth but after death there's no more chances.
