I don't think there is any evidence or even proof of a literal hell of eternal, fiery torment. It contradicts any sense of justice... what would be the point in people suffering for eternity? Are they learning a lesson for their betterment? It also contradicts the laws of love and mercy.
But we can be in 'hell' now if we are separated from the love of God. The parable of Lazarus and the rich man more likely meant that the Kingdom of Heaven was being taken from the Pharisees/teachers/hypocrites in the law who had the kingdom and abused it; and then given to the poor man (humble in spirit, etc.) who would produce its fruit. Ie... care for the poor, show mercy and love, etc. The loss would be a torment... hence all those sayings about gnashing of teeth (envy/jealousy) for those thrown outside the kingdom.
Since Jesus came and condemned those hypocritical teachers, whilst favoring the poor and the sinners who were willing to hear his message, this seems to make more sense. At least to me.
