True but emotions help decision makers decide whether a certain element of the decision is relevant to the particular situations. Luffy in this situation was only driven by vengeful rage and some level of pride in wanting to be The Pirate King.

In Enies Lobby Luffy was driven by emotions to defeat Rob  Lucci but in that case it helped as he could "sense' that by keeping the fight one on one, Lucci couldn't go off and kill the rest of Straw Hats. I

Luffy is shown to willingly to flee certain battles (e.g Smoker, Fuijitora)  if he'd ran away from this one and saw that Tama and the Sunny Crew were fine, then he'd have no reason to attack Kaido and weren't be now imprisoned.
