No shit, moron. Rocks wasn't king of the world yet and only recruited strong subordinates.
Do you think it's coincidental the dude that wanted to dominate the world didn't have any followers that were actually loyal to him? He recruited most of his crew through Davy Back Fights. NONE of them tried to save him in the end. They abandoned him at his time of greatest need.
If you paid attention, you'd know Rocks and Roger are mirror images, you imbecile. Roger was born in the East Blue, Rocks in the West Blue. Roger was immortalised in legend, Rocks was erased from history. Roger embraced death on his own terms, Rocks was rushed into an early grave. Roger died smiling, Rocks died confused and crying. I can keep going.
Pay attention, dumb mfer.
