So in the end Luffy is driven by fate, it is his Destiny to become Pirate King, to destroy the WG (Im-sama and World Nobles) and to fullfill Joyboys will (will of the D.).
Luffy strives to be the PK, in his owen words to be the freest man but in the end he would only be a tool, a slave if not the biggest slave of fate. Every action of his are set, the outcome is set, he thinks his free in his actions but it is only a illusion, he has no true freedom and will never reach true freedom. I feel pity for him, cause his dream to be the PK, to be the freest will never come true.
In the end we're all slaves to fate.
Well sucks
have a nice day every one
