dude he said that because his body is becoming more like his siblings not like he is losing his emotions and the fact that you say is that sanji get powerup from his father who he is hated . Yes sora wanted sanji to be human because of the sh*t that judge did(taking emotions from them). She is fine with reiju. It is repeatedly being a theme during the whole new world for multiple characters . First zoro ,before timeskip when he learned of luffy's code,then he decided to having mihawk as his master(even beg him). even though he hated that. Same with nami after timeskip,but she is more of deciding to leave hate on fishmen. Her first interaction is hacchan,caimie, then even jimbe who is indirectly related to nami's disaster. Nami decided to leave that. Momo too he hated kaido and also being like kaido but he became like kaido and he learned to accept the reality. Even chopper he worked with ceaser who he hated and accepted the reality even though he hated it . ceaser invention can make him stronger. The fact that you can't accept the entire running themes of timeskip is on you.
