What type of sinners are being punished in the fanal circle of hell?

In Dante's "Inferno," the final circle of Hell, known as Cocytus, punishes the treacherous. This circle is reserved for those who have betrayed others, including traitors to friends, family, country, and benefactors. These sinners are frozen in ice, reflecting their cold-heartedness and the ultimate betrayal of trust. The severity of their punishment underscores the gravity of their sins against human bonds and loyalty.
