Pretty much. Still believe he shouldn't have killed her, but if this is the case i can definitely understand he snapped at some point.So they robbed the dude multiple times, harassing and attacking him all the while? And he's reported this to the authorities and no one helped him those times he reported?
That's kinda atrocious. He wanted his harassment to stop, and no one was helping him. Is he wrong for taking matters into his own hands? No. Is he wrong for killing the lady? Well no, she robbed him 'multiple times'. She got what she deserved.
