Was this retaliation justified?

Recently this article was brought to my attention by a woman who then indicated that she felt that an asshole was getting his due. In a nutshell, the article tells of a man who tried to rob a hair salon, was overpowered by the martial arts practicing salon owner, then kept captive in the back room for a few days, fed Viagra, and used as a sex slave. There are questions in the article and links about the real whens and wheres of this, or how accurate it is but that is not my point. I want to know if the Jelly community feels that the salon owner was justified in behaving this way to the would be robber. Nowhere does it say that he had any intention of assaulting the women sexually.

So, jellies, was her behavior justified or not?
