Judge Dredd

Judge Dredd is a dark antihero from the sci-fi comic 2000AD as well as a number of spin-off merchandise (including a live-action movie, where his character was altered heavily).

Judge Dredd is traditionally portrayed as a character that can either be seen as an extreme example of an antihero or a full-fledged protagonist villain depending on your moral views - Dredd rules over a dystopic future in which he and fellow "Judges" deal out instant justice to innumerable criminals, malcontents and monsters.

Judge Dredd is known to hold the law dear and will never bend the rules for anyone, however he does value innocent lives - in fact he will fight viciously against those who seek to harm the innocent (if only because one of the central rules of being a Judge is to safeguard the "innocent").

This doesn't mean Dredd is an easy character to get along with, he is easily considered as bad as characters such as the Punisher or Spawn but in the end (much like both Punisher and Spawn) he fights on the side of order: it is important to note however that Dredd is traditionally depicted as fighting on the side of Law and not "Good" - making him a questionable hero but popular nevertheless.
