566 taking the money is different than Deano's million dollar choice

The 1 million Deano and the others were offered was never going to be split among the team. It just went back to Mr. Beast. The only decision was whether to eliminate a group of players, and the entire point of all of these games is to eliminate the other players!

566 taking 650k was a selfish act because it was an amount that would have been split. It was not a "game move" for purposes of winning the game.
