In the Christian theology of Emanuel Swedenborg (1688-1772), which is one of my primary areas of expertise, the issues raised in your question fall under the general category of divine providence.
Swedenborg defines divine providence as "the form of government exercised by the Lord's divine love and wisdom" (Divine Providence #1).
Under that overall umbrella he includes his book on the subject the topics encompassed by theodicy, the problem of evil, and the problem of hell in the face of an eternal, omnipotent, and beneficent God.
For Swedenborg's approach to these problems, I highly recommend his book Divine Providence, originally published in Latin, Amsterdam, 1764. It is available in English translation, and in many other languages. For my recommendation of the best contemporary English translation, see my brief book notice and review here: Divine Providence, by Emanuel Swedenborg.
If nothing else, this book will help to round out your researches into this fascinating and highly debated topic.
In particular, Swedenborg distinguishes between "laws of providence," which define how God acts in relation to people whose lives are focused on what is good, and "laws of permission," which define how God acts in relation to people who are focused on what is evil.
For the good, according to Swedenborg, God provides every opportunity to continue moving forward spiritually so that after death they will live in the eternal joy of heaven.
For the evil, according to Swedenborg, God makes every effort to provide opportunities to reconsider, repent, and change course; but God will not violate the free will of the person by forcing a change of heart, mind, or destination.
In Swedenborg's theology, hell exists not because it is God's will that anyone should go there, nor because God desires to punish the wicked, but because humans who choose evil over good insist upon creating and living in a hell that reflects their own evil choices. The punishments of hell are not meted out by God, but are self-inflicted by the evil spirits themselves, and by other evil spirits in hell.
As in many other theological analyses of the problem of evil, in Swedenborg's theology it hinges on human free will, which in his view is a fundamental component of our humanity. I think you will find, though, that in Divine Providence Swedenborg offers a depth of analysis that is rare in traditional Christian and philosophical treatments of the subject.
