Dante's Inferno is much more than just embracing the nine circles of hell, our existence is about finding the truth and light, the darkness will always follow us, the vices will be too irresistible to refrain from but then there is a light inside all of us that helps you finding the real you. I have known you long enough to say that you can kill the demon, no one else can. You know what is real you just need to be strong enough to accept it.
Dante's Inferno is purely the illustration of life after death, and the 9 circles for those who have committed the conventional sins including the seven deadly ones. My own perception of those was a little different – hear this: they're not sins, they're our vices winning over one circle at a time, given that we let it. It is only by knowing the enemy we defeat it. That's the little hint I can give you. Rest is for you to make out 😉
