Well, Delilah was the courtesan of Gaza who corrupted Samson long enough to end up finding out the source of his strength and cut off his hair, rendering him helpless. Samson was in his own way corrupt enough to be taken advantage of by Delilah and Samson’s penance was to end up dying after pulling down the evil temple. Delilah did redeem herself in the end by refusing to escape to safety, dying with Samson.
LOL! That was from the Victor Mature movie. I always thought the same thing (because movies of yore were like the Internet of today -- 'they wouldn't steer me wrong'). You actually read the book of Judges and the last you read of Delilah is when she betrayed Samson to the Philistines.
Redemption is always possible (Thank God!), but there is no record of it for Delilah.
