How does Charming Man even become part of the team? He literally ''killed'' Dragona in front of everyone and they suddently recruit him? How does that make any sense?

Edit: in conclusion after reading your comments this has happened with kakyoin, we get it but kakyoin was literally posessed and Charming Man tried to murder all of them for a stupid reason, he's defo betraying the gang further on the story and jodio shouldve killed the guy who stabbed his brother in the neck and tried to excuse it as ''i wanna find my brother with the rock'' like sybau atp gng
