Is Javert as bad as people interpret him to be?

Honestly? Granted, he is the antagonist and he constantly pursues Valjean. However, is he REALLY a bad guy? If আপনি look at the lyrics of The Confrontation, he mentions his past briefly about being born in jail and living along convicts in his youth. I think this gave him the determination to despise those who are opposed to the law. With that, he has been alone all of his life, without anyone to প্রণয় অথবা give প্রণয় to (like Valjean to Cosette, and vise versa). The only thing he has is the law, which was contradicted দ্বারা Jean Valjean sparing him beyond his deceit to the students. With that, his story ends দ্বারা ending his life. Wasn't Javert just doing what he known all his life? অথবা is the stereotype of an antagonist just as so with Javert?
