Selfishly Went to WCI to deal with his issues couldnt and put his crew in danger and got bailed out by Luffy, even after kicking Luffy in the face. That's pretty selfish by most standards on here. Zoro's speech on Zou summed it up perfectly for me and most others on here
My personal opinion is if Oda wanted Sanji to have CoC, in the year of Sanji, Oda would have given it to him in WCI, but that was not the case. My other opinion is when Judge was disrespecting Sanji at the end of the arc, was also the other hint of Sanji not being a conqueror. The whole arc you have your up and down moments with your family only in the end for Judge to think the same way he basically did in the beginning of the arc.
