Hell: punishment or self-inflicted? What if it is both, especially if we keep more than the sense of poena in mind -- that it is a privation. Secondly, God's judgment is not a distinct act from His being or His love.
The Heresy of Hell as Self-Inflicted by Charles Robertson
I also note that while the title calls it a heresy, there is no evidence that it is so, other than that the position that Hell is self-inflicted seems to go against Scripture. And this only if we hold that Hell being self-inflicted contradicts it being a punishment. But more likely than not supporters of Hell being self-inflicted can offer an explanation of how it is still a punishment, or harmonize it with the words of Christ.
