The answer lies in what hell (Sheol, Hades) truly is. You must go beyond what you may have already been taught. Dante Alighieri may have put the bug in the ears of the Pope and the early Church, passing it down to others that they, too, may believe. But it's the Bible that teaches us that such is not, and never has been, the personality of Almighty God. Some keys to consider when giving your answer: First, think of free will. Second, consider the One who gave it to us. Third, think of God punishing us for exercising the free will he gave us. Fourth, if God is not vindictive, what purpose does it serve to create the kind of hell that most people today believe in? But even more telling, hell, as most perceive it to be, is how humans decides whose sins are more evil than their own. Research this question beyond what you may have been taught and those that taught you, and your answer will be correct.
