He basically grew up in poverty and hardship, and despite being a thief for ages apparently never really made much money off it. he saw his chance with the scroll and wanted to get rich himself, thereby ending his state of misery.

Besides, it's a lot easier to pawn stolen weapons that can easily be traced to Konoha, when you don't have nosey allies.
