I'm feeling like this is about a deceiver who has ensnared our narrator, and he feels that he is completely justified in getting to judge her and say atrocious things about her because she has proven to have such little worth. He could almost be warning of this cruel person to others, which is why he seems to think that she's not going to change and just keep hurting if she gets the chance. He definitely hates who he's talking about.
