It'd be more of an 'enemy of my enemy is my friend' kind of scenario. The strict trade embargoes enforced by the Empire make it hard for my character to get his smuggling/arms deal business off the ground. Plus, he's not really in it for charity. I'd wager he stumbled onto some Jedi, smuggled them to sanctuary and leveraged an ongoing deal to help transport goods/medical supplies in exchange for credits/trade goods.
