Luke a mercenary?

[Ando Huntre]

I was watching Star Wars A New Hope. At the end, at Yavin, Luke is trying to get Han to help them. Han offers Luke to join him and Chewie. He said that Luke was good in a fight. What do you all think would happen if Luke would have left with Han?

The Rebellion would have been more than likely destroyed but Luke probably couldn't put that on his conscience for long or Obi-Wan would contact him through spirit and convince him to train as a Jedi more.

Or he gets captured by the Empire or pirates later since a guy running around with a lightsaber doing smuggling work would not go unnoticed for long.
