The message of Christianity (as proclaimed in the Bible) is that the cause which results in the effect of going to hell, is sin. Jesus died because He is The Way to be forgiven, He is the provision which took your sin on Himself. Without Jesus, yes a person will go to hell; but not because of Jesus, but because their sin demands it. Jesus is the cure, not the curse.
For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
