That wasn't a justification, it was an explanation of how there's no family to step in and make him get help!
And you're making a huge assumption there by implying that she's into him and staying with him eve though he physically or mentally abuses her! (Not to mention your clear lack of knowledge of why women don't get out of those types of relationships.)
You're really overreacting to things lately.
Too much 'roids perhaps?
