Here is the meaning of the word they used for Judas's destruction.
Cognate: 684 apṓleia (from 622 /apóllymi, "cut off") – destruction, causing someone (something) to be completely severed – cut off (entirely) from what could or should have been. (Note the force of the prefix, apo.) See 622 (apollymi).
684 /apṓleia ("perdition") does not imply "annihilation" (see the meaning of the root-verb, 622 /apóllymi, "cut off") but instead "loss of well-being" rather than being (Vine's Expository Dictionary, 165; cf. Jn 11:50; Ac 5:37; 1 Cor 10:9-10; Jude 11).
Judas was cut off from what of could've been…
The word for Judas's destruction is the same word that is used in Romans 9:22 for "vessels of wrath fitted for destruction." God alone determines who is to be a vessel of mercy or a vessel of wrath.
And if there's any consolation what may happen to Judas, I would encourage you to read Romans 9-11.
After you have read it, pay particular attention Romans 11:32, where we read,
For God has shut up all in disobedience so that He may show mercy to all (NASB 1995).
