Meliodas' journey as the leader of the Ten Commandments is such a fascinating mix of duty and personal conflict. At first glance, you'd think he'd regret it given how much he sacrificed—his relationship with Elizabeth, his own morality, and the trust of his allies. But when you dig deeper into 'The Seven Deadly Sins,' it's clear that his time as their leader wasn't just about power. It was a twisted path to understanding his own darkness and, eventually, redemption. He had to become that version of himself to confront the Demon King and break the cycle of curses.
That said, I don't think regret is the right word. Meliodas carries the weight of his actions, but he also accepts them as necessary steps. His leadership of the Commandments forced him to face truths about his nature, and without that, he might never have grown strong enough to protect what he truly cared about. It's messy, brutal, and heartbreaking, but regret? Nah. More like a grim acceptance that sometimes you have to walk through hell to reach the light.
