Deathstroke is a character that I prefer to see used as a full-on villain. There have been some attempts to cast him in an anti-hero role, but that never sits well with me. I saw him commit too many despicable acts in the pages of New Teen Titans and elsewhere to ever want to have to root for him in a story. I'm all for a good redemption arc in comics, but it has to be done with the right character.
Starting tomorrow, STF's longest continued story yet - a 7-Parter!
