In the recent chapter she said that she couldn't disobey her father judge but she also said she switched the cuffs I understand its possible big mom gave the order but I though it was judge what do you think
I bet not everything he says is an automatic obey, like if they were to rebel against him, he could "overwrite" them and control them... But he has no reason to for every little thing as he thinks he can trust them.
But that's just my guess..
I believe that if given a direct command she can't disobey but if its not a specific order I think she has some room for free will (such as putting on dud shackles). It's probably also another reason she wants to die as it would release her from being a slave to her father and family. It's probably something to do with the lineage factor which you also see with the Germa clones whom will do anything the Vinsmokes say, even putting themselves in the line of fire.
