I would. My hatred of sues dwarfs even my love for the marines. Also, if it was Rebbeca that ate the fruit and then pulled Ace's move, you'd be all agreeing with me.
I don't think so. If rebecca did it, I think people would be pretty pissed, but not like if Sabo did (or burgess). I mean, based on him being on par with ace when they were kids, you can assume that he's got same potential as ace and it's not surprising that he could handle such standard move like hiken on first try. If you're referring to tashigi who couldn't do the same back in PH with smokey's body, I'd say Tashigi was just not in Sabo's level of strength (both physical and mental, and potential) to handle things like logia fruit that fast.
