I though about that but then I'm pretty sure Luffy figured out that Grap essentially let him pass by at Marineford (he knows he couldn't have punched him that easily). So if Garp didn't do anything to impede Luffy from getting to his brother than there's no reason for Luffy to resent him for that. And that is why I didn't use that argument. However, I don't think Garp letting Luffy get by changed his opinion of him.
