Akainu notoriously attacked WB while the old man was having a heart attack, and it is generally considered a dick move and dishonorable to attack someone while they’re having a heart attack. Akainu also, without objection, lied to Squard in order to trick him into weakening WB with a sneak attack. Akainu also chose to taunt Ace in order to lure him away from the rest of the WBP instead of just attacking the WBP head on.
