i know of NO verse in the bible that says "damned" and classic scary movies are always the scariest! have you ever seen the movies by Frank Perretti (sorry i do not know how to spell that lol)
16 He that believeth and is baptized shall be saved ; but he that believeth not shall be damned . (Mark 16:16 KJV)
23 And he that doubteth is damned if he eat , because he eateth not of faith: for whatsoever is not of faith is sin. (Romans 14:23 KJV)
12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness. (2 Thessalonians 2:12 KJV)
This is not the same thing as using the word as an expletive ("Damn it!").
