You know how a lot of bandits in fantasy novels actually don't have a bad reason for becoming bandits? They were starving farmers and their life was being exploited by nobles and bandits. I mean it doesn't excuse their crimes expect theft partially. Maybe you'd wanna be a Robin Hood type then, but you don't have any weapons, armor or training so you can't actually attack pretty much anyone who has it coming as they will have defenses so all that's left is small merchants and villages. What would you do if you were a starving exploited farmer?
