Punisher War Journal (Vol. 2)

When mobsters slew his family, ex-marine and current NYC Police officer, Frank Castle vowed to spend the rest of his life avenging them. Trained as a Marine and equipped with state-of-the-art weapons, he now wages a one-man war against crime as the Punisher.

While technically a criminal, The Punisher has been both hunted and tolerated by the Superhero community, because, while flawed, he really is on the side of the angels. So while most of the heroes with whom he has come into contact with over the years object to his methodology, they allow him to continue to operate as he does have an effect on crime (usually by killing bad guys).
