Will one piece king Tragarfaro die in the end? Why did he form an alliance with Luffy? What about his former men?

According to past practice, Luo will not die. And according to the plot development, Luo is likely to become another big arm of Luffy. Now Luffy's cards are the original white beard, red hair, female emperor, revolutionary army and fisherman. Luo, clowns and fortune tellers are still unclear. They were placed in the League because Luo's enemy was Flamini Mingle of the Seventh Sea. Luo's strength is not enough to compete. As for Luo's crew, I personally think it's an ambush. As for what to do, it's hard to guess, but according to Luo's character, what his gang did should be very important to attack Flamenco.
