Ozzie:
I specifically didn't name the "son of perdition". The text doesn't mention Judas at all. Further Paul seems to indicate that he was yet to come.
(John 17:12; 2Thess.2:3)
Mark.14:21 does seem to pronounce a curse on Judas, though.
Taking the same vein, though, what about the Rich man and Lazarus?
Or how about Simon Magus, who was cursed by Peter, but asked that the fate of perdition not fall to him (or words to that effect )?
In the circles I roam folks have the idea that King Saul fell, too, because of the incident with the Witch of Endor. Personally I'm not so sure at all. I wouldn't be dogmatic, but I don't think the text is anywhere near so certain.
Apoleia (Strongs G684), often translated "perdition", is also found in the following places:
Matt.7:13; 26:8; Mark.14:4; Acts.8:20; 25:16; Rom.9:22; Phil.1:28; 3:19; 1Tim.6:9; Heb.10:39; 2Pet.2:1, 2, 3; 3:7, 16; Rev.17:8, 11.
It may have a root from Apollum (Strongs G622), from which we find even more specific texts.
