The Rebellion offers a sense of family, (there is also safety in numbers) and it’s better than going back to smuggling drugs for a giant slug? 😉
I certainly agree, but this was the very thing Han struggled with through ESB. At the end of which he was frozen in carbonite. This also does not explain why Leia was reacting to Han leaving the way she did (and the way he responded) if he had already accepted being a Rebel in the film.
So while Han certainly comes to that realization, as evidenced by him as a Rebel General ROTJ, the film skips over any scene where he actually acts upon this; the [natural] resolution to his arc in this respect.
The deleted sandstorm scene actually serves this purpose better than nothing (and the comm call of him thanking Luke). If they’d paced the over all film better (such that it didn’t drag in Jabba’s Palace sequence and at the Ewok village) I think it would have made a better addition to the film.
But that’s just my opinion, again.
Here’s another topic to provoke discussion: I personally think the entire Ewok plot line is superfluous to the story (though I have no real problem with the Ewoks themselves; they could have been Wookies and still the issue be the same).
Queue drum roll and my follow-up line of reasoning; I’m about to get a bunch more strongly worded disagreements. 😉
