[Blackbeard D. Kuma]

^ It's more like Blackbeard was destined to get the darkness fruit despite the fact that he didn't actually find it himself. Even though Thatch found it, it wasn't "meant" for him. So being the opportunist that Blackbeard is, he forcefully took matters into his own hands. Remember, a big part of fate that Blackbeard and his crew refer to is also luck. It was "fate" that Blackbeard and his crew survived Magellan's poison at Impel down, and that's all because Shiliew just happened to be there with the antidote. It's almost as though things are "rigged" for Blackbeard to succeed.
