Have her family teach her that stealing is bad, helping others is good. She could perhaps help another kid get back something from a bully, realise that sometimes force is needed despite the pacifistic way her parents/caregivers may have taught her, and she goes on to become a sort of vigilante. Sometimes people just do things with no real reason other than because something in their brain tells them it should be done - helping others by forcing the oppressors/discriminators to stop being douches is something some people would do simply because they can see the results happening in front of their eyes.

That's what the White Fang has been doing; since peaceful protests supposedly weren't working, they turned to fear tactics and got the Humans to 'improve' how they treat Faunus. We don't know if it was actually necessary for them to do this, but it's gotten them results that they can see faster than the peaceful and pacifistic way would have.
