And while they were going to buy, the bridegroom came, and those who were ready went in with him to the marriage feast, and the door was shut. Afterward the other virgins came also, saying, ‘Lord, lord, open to us.’ But he answered, ‘Truly, I say to you, I do not know you.’
Matthew 25:10-12
Some deathbed conversions might be sincere, but I suspect that most of them are just charades. If a person says, "I'm going to keep doing what I want right up to the last minute, then I'll tell God I'm sorry and didn't mean it," he's clearly intending to lie to God and God is never fooled.
If you mean to repent, then repent. Or else you don't really mean to repent.
