Thanks for dropping 1081 spoilers that early
They aren't ready for Sengoku to go full Buddha on Blackbeard!
You know how the original concept for One Piece had Peace-Mains and Morganeers, good and bad pirates? I think Sword is foreshadowing for Oda making a group of pirates that works with Sword, and that X-Drake and Law working together (and their connected plotline in general with Sengoku) has been leading up to that.
Law openly goes out of his way not to kill people generally... he's really NOT evil, like, at all, which is why it's so funny whenever he tries to act like pirates shouldn't do good things.
What would you call that group? Spear? IDK.
