User blog:Mythical zoan fruit enthusiast/I'll never forgive you!!! Unless...

So recently I rewatched some of One Piece from around the beginning of the series all the way to the end of the Alabasta arc and learned a few things in retrospect. One was how much I hated Usopp, two was the ridiculous power gap from Luffy & Zoro to Sanji and the equally substantial gap between Sanji and the rest of the crew. The last thing(which is the point of this blog) was that Luffy tells a lot of people that he'll never forgive them. A lot of people.

From ones he obviously was gonna forgive like Robin and Zoro to considerably less likely candidates like Galdino and Crocodile his word didn't mean a whole lot.

Taking this concept to more current villains I'm gonna ask you who do you think Luffy is more likely to forgive Sakazuki or Blackbeard? Sakazuki obviously killed Ace and was willing to chase Luffy to the ends of the earth while Blackbeard was the pirate who killed Ace's friend, captured Ace, turned him into the Navy, and killed his "father" Whitebeard.

Who is Luffy more likely to forgive and in what situation would he allow himself to side with one or the other even if only in a temporary alliance like with Crocodile?
