@BlackLegFring @llama sure, Luffy has some PTSD from Ace' death and the wound he received in the process, but there is still no personal grudge against Akainu, as in "I need to revenge Ace' death". He accepted Ace death. After blaming himself, he realized that he still has his Nakama. Ace lived and died like a pirate, he was killed fair game. It's not like Blackbeard killing a Nakama, forcing Ace to pursue him. Or like in the case of the Scabbards holding grudge against Kaido. It's not the case for Luffy against Akainu.
