You omitted the caveat, "in my unlearned opinion"
"And account the longsuffering of our Lord, salvation; as also our most dear brother Paul, according to the wisdom given him, hath written to you: As also in all his epistles, speaking in them of these things; in which are certain things hard to be understood, which the unlearned and unstable wrest, as they do also the other scriptures, to their own destruction." 2 Peter 3:15-16
The truth does not need a caveat.
If you were blind you would have no sin, but because you say ‘I see’ your sin remains.
‘wrest, as they do also the other scriptures, to their own destruction.’
You deserve your destruction.
That passage has nothing to do with purgatory, in my very learned opinion.
