Ah, see, I figured they did have to account for what happened to her to see if they could figure out if she'd been captured and if any of the Imperials had gotten back to their base, because if the information that suspicious people/Leia Organa were there had gotten back, the Imperials would probably change their whole defense. Knowing what happened to Leia could help them decide whether they could continue on normally or assume the Imperials knew they were there. So I saw it as important to the mission as well as a personal thing.

But I don't know whether that's what Han was thinking, so you're right.
