How can a loving God condone judgment and Hell?

This is actually a class-based question, likely asked by those of us living in the safe confines of the West.  

Not long ago, we were in rural South Africa interviewing Christians who had converted from animistic/black magic religion. We asked this amongst many other questions: "What is your favourite verse in the Bible?"  One answer stands out in my mind to this day.  It came from a muscular, intimidating man, who carried intensity with his every word.  In a less friendly circumstance, I would have been afraid of him.  But get this, his favourite Bible verse was "Thou shall not kill".

For those trapped in the cyclical environment of revenge and violence, the God who says in Deuteronomy 32:35 "Vengeance is mine" offers a way out.  Recognizing ultimate justice exists and that it will be carried out by an all-powerful God, gives both hope and reason to restrain oneself from the natural impulse of getting even.    

To the oppressed, the relevant question is not: "How can God condone judgment and Hell?" It is: "How can a loving God NOT be about judgment and Hell?"  

And our response should be that of Paul the Apostle in Romans 12:19 "Do not take revenge, my friends, but leave room for God's wrath, for it is written, 'It is mine to avenge; I will repay.' says the Lord".
