Regrets.
Whitebeard was finding it hard to think. The fact that he was thinking was nothing short of a miracle, with half of his skull and brain ripped away, but even he was beginning to give into biology. Even if he did wipe out the Blackbeard pirates, he probably wouldn't survive long at this rate. But that was fine. That was what he predicted would happen anyway. He had no regrets about that.
That's not to say he didn't have any regrets though. He regretted letting Blackbeard in the crew for one thing. If he hadn't, then this entire situation would have probably not happened at all. Probably, although Blackbeard was the kind of unpredictable man who may have ended up doing it anyway.
He regretted letting Ace go after him. He should have discreetly asked Garp to deal with him, or else simply let him go until he blundered onto the marine's radar then sat back and watch as the world government declared war on him. But it was too late for that now, and he wasn't even sure that he could stop Ace from doing it anyway.
He was annoyed with himself for creating those two tsunamis. He had known that Aojiki would freeze them, of course. In fact, he had been counting on it. He wasn't damn foolish enough to wipe out his entire army with his own bloody attack, but he was foolish enough to help create two massive ice walls to block his own escape. Stupid, stupid, stupid.
He had plenty of regrets throughout his long life. But his biggest regret was his last. He regretted that Blackbeard was standing before him alive. He lashed out, striking him with his bisento, and grinned one last time as the man fell back, blood streaming from the wound.
"Kill him!" Came the traitor's order to his crew, and Whitebeard felt swords and bullets slamming into his body for the last time.
He regretted that he could no longer move his body. He…regretted…
