The problem I see is that you are starting from a false premise, namely that man can be deserving of either Heaven OR hell based on his own actions. You can never be good enough to "deserve" Heaven nor bad enough to "deserve" hell. The sole factor in your eternal destiny is this - what is your relationship with Jesus Christ? It is Christ's sacrifice that washes away or sin and makes us acceptable to God, not our good works. It is our rejection of that sacrifice that condemns us to remain in our sins and dooms us to an eternity apart from Him.
OK, thank you
