Did t pain sell his soul?

Your soul is not yours to sell. However, according to the Christian religon, unless you accept Jesus Christ as your savior, your soul will not be with the Lord in Heaven when your body dies. Sadly, that leaves hell as the only other option.

You can opt to not give your life to Jesus and that will condem you to hell, but God allows you to redeem your soul at any time during your life by accepting Jesus as your savior. Even at the last minute. So you can't "sell" your soul. To sell it would imply that you no longer have it.
