Why does Arthur not make peace with Lancelot?

Arthur does not make peace with Lancelot primarily because of the deep betrayal he feels after discovering Lancelot's affair with his wife, Guinevere. This act of treachery fractures their once-strong bond and leads to a sense of irreparable damage in their friendship and loyalty. Additionally, Arthur's sense of honor and duty as a king compels him to uphold justice, making reconciliation difficult despite his personal feelings. Ultimately, the conflict reflects the tragic consequences of love, loyalty, and betrayal within the Arthurian legend.
