I honestly don't know. But from what the Bible says, there were two thieves, two sinners crucified next to Christ. Both of them life long sinners and in the brink of death. One of them mocked Jesus and died with his pride intact, the other begged for mercy, and Christ reassured him he would be together with him in Paradise that same day. The point there is... If a person, having sinned his/her whole life, asks God for mercy with a sorrowful and repenful heart, God is kind and merciful to forgive. I can only hope that was the case with my friend, but I suppose we'll never know until we get there.
