What would you do if someone tried to rape your sister?

That seems to be the discussion of the day after this video of a man mercilessly beating another man who allegedly raped his sister went viral.

The fight begins with both men on their feet but within a few seconds the brother of the accuser throws the alleged rapist to the ground and wails on him, then kicks him in the head a couple of times for good measure.
