The Goat Sin of Lust was my least favorite of the team, but he definitely is more than meets the eye. The weirdest of the Sins, he isn’t super strong but he’s very talented in memory manipulation.
While technically a doll, he is capable of real feelings. He did love Nadja Liones many years ago.
What was really surprising was that (like Meliodas) he was once a member of the Ten Commandments.
Though it’s rather obvious that he acted differently back then.
Mostly because it was really his “father” (also named Gowther) that was using his body to interact with the outside world.
I did feel a lot of sadness watching his creator tell him goodbye as his great deception that ended the holy war took his life due to sheer power required.
He does spend the majority of the end fixing the aftermath of his dad’s good intentions.
