Wrong. Life is about perfecting.

Repentance is about returning to a starting point after you go astray. Repenting alone is only the start. False doctrine has been preached to lead people astray. Many think that their spirit can be saved on dead bed just by accepting that they had done wrong all their lives.

The 2 thieves by the side of J.... is taken out of context. You don't get capital death penalty by Roman law of the time for mere stealing. Those two try to steal something. One of the thieves realize "the real deal", the one that would return to Cesar what is his, instead of stealing!

Hints: many men with that age at the time of history, has Messiah delusion because about 30 years prior, majority of boys got killed! So these men would already live their lives in certain way of lives before being on their death bed.

So yes, you better repent as soon as possible, so you still have time to perfect this life.
