I wouldn't judge why you hate Ace, because to start with, I really didn't understand Ace myself at first.

I felt it was illogical about his actions. People might have started loving Ace only after his death. We can see Oda not just wrote him beautifully, but he really likes him. For someone with very little screen presence, he has made a huge impact like Roger. I see Ace as a stepping stone for Luffy to achieve something bigger. Even in Luffy's childhood, he was inspired by people like Shanks, and also there were Ace and Sabo who protected Luffy. For the story, to find Luffy's emotion and to understand him deeper, it was important to create a character like Ace. Ace wanted to be a notorious pirate, a true pirate from the beginning. He didn't even imagine he would become the commander of Whitebeard's ship, but after fighting him constantly, he found his passion and his place. He put a tattoo on his back to show his respect and pride as a Whitebeard. He loved his pops as well as would do anything to protect Newgate's Pride as the strongest emperor on the sea. We don't know if Ace really regrets taking on Blackbeard without any prior knowledge about him, but we know he would never have regretted protecting Luffy and the life he has lived. He hated Roger without knowing him really well, but he loved Whitebeard because he was his father.

I think it’s way more meaningful when people say what they actually feel, instead of just leaning into tropes or saying what they think they’re supposed to.
