I haven't read the original book, so I don't know much about the love and hatred of the characters through the movie version. I went back and read the various explanations of the diehards before I can understand Gus's celebration after the victory of Dordore. In those words, Gus hoped for an equal relationship, but Griffith couldn't give him what he wanted, so the final result could only be to let the brothers who used to be side by side break up.
Looking forward to the final chapter of the Golden Age.

After watching the second part and then re-watching the first part, I found out that Gus's departure has actually been foreshadowed in this episode, and he will leave Griffith sooner or later. As he said at the end, when he heard what Griffith said, what he wanted to do was to see how far he could go, when in the end Griffith was one step away from his goal When he was far away, he chose to leave, but he didn't know that this step was unimaginable.
