Doesn’t matter about liking. The pirate world is one of honor. Hell whitebeards whole thing is you don’t betray those on your ship.

Whitebeard would never betray the Rox pirates. Goes completely against his character.
And there's no reason why he didn't adopt that philosophy after betraying Rocks. He even said he had bad experiences with his last crew and its even stated that the Rocks pirates killed one and another constantly, and Whitebeard would ofc hate that if Rocks was allowing it to happen, considering he started a war over BB and Ace.
