Does this guy have the recklessness or hot-headedness of his bros

Luffy
Ace
SABO

Does Sabo have the same recklessness? Did he have it as a kid? I can't remember. As an adult he seems far less reckless, though he may have shown a streak during the tournament or by fighting Fujitora - but he probably had good reason to believe he could hold his own against an admiral.

Obviously Ace showed recklessness against Whitebeard, Blackbeard and Akainu.

Luffy we saw it in basically every arc. Running straight into Kuro's place IIRC, going straight into Galley-la, Enies Lobby, fighting Crocodile, punching Krieg's spiked cape, three admirals, celestial dragon.

He definitely has it to an extent. He would have gone to Marineford to try to save Ace even if it was a hopeless situation. I don't think either Ace or Sabo match up to Luffy in this regard though.
