Background: Mr Bosu, an ex-rapist, was hired as a killer to kill the father of his rape victim. He posed as a detective and wangled his way into Miller's house.IT TURNED OUT that Frank Miller was no dummy. Mr. Bosu wasn't sure what he'd expected. Maybe someone smaller, more shrunken, more beaten by the lousy blow delivered to his family earlier in life. Someone more like his own dad.

I'd like to know whether Miller was beaten physically or emotionally. I'd say it is about his physicality as the description preceded by it is his smaller, more shrunken appearance.
