Canto 28-34

Ahh, the "sin" of betrayal will land you in the farthest depth of hell, in which Dante details in Canto 34. Here lies the ultimate three sinners (as well as many others), Judas Iscariot  who betrayed Jesus, Cassius and Brutus who betrayed Julius Caesar, and finally, Lucifer for betraying god himself. The sinners here are all trapped in ice, with Lucifer's beating wings constantly keeping it cold, icy, and windy. I personally do not believe the punishment fits the crime because being frozen and not being able to move is a little much for betrayal. However, the three sinners mentioned did commit huge acts of betrayal, so, having them being frozen in ice and not being able to move does prevent them from harming others. Did I mention that these three are constantly being torn apart but never killed by Lucifer? How fun! The other canto in the ninth circle of hell is the 33rd, people who have betrayed their family or their country, and they are trapped in a frozen lake, like the ones in 34. But here's the other part of it, whenever they cry, their tears are frozen to their face, which is extremely painful. The ironic thing is that they themselves cry because of the troubles and tears shed in betrayal. Canto 28, the final canto of the 8th circle, houses falsifiers: alchemists, perjurers, importers, and counterfeits). Their punishment is that they are each infected with some disease because Dante viewed them as a plague upon society
