Kuma "agreed" to the deal because after a childhood of enslavement and seeing his parents get killed he has an inferiority complex. He calls himself "a spineless pacifist" which when you think about it makes no sense because why would a real pacifist use violence to dethrone King Becori and join the Revolutionary Army? Kuma questions his right to live and wants to "be of use" to others which clearly stems from his slave mindset. One could argue that a person who has been victimized and manipulated to dislike himself to such a degree cannot consent willingly. All in ll, Kuma is a racist stereotype of a black enslaved person/an Uncle Tom. I'm really amazed tbh. Oda surpassed himself, it took him only 4 chapters to build and subsequently deconstruct a character in the most nonsensical and idiotic way.
