There are five people who all live similar lives, and the lead has reason to believe that one of them is planning a large scale attack on a city, but can't prove it. When the lead tries to get the authorities involved they don't believe the lead and ignore the warning. The lead decides to kidnap the five and interrogate them, but they all insist on their innocence even in the face of torture. The lead starts killing them off one by one in hopes of scaring the others into confessing. Only when four are dead does the fifth admit to his plans and there's just enough time to stop the attack, but now the lead is a killer and can't go to the police anymore. That's the basic idea that wouldn't leave me alone last night, but before I g any further on trying to plan it out, I'd like some different opinions on the character and his actions. Figured, best to get them now, before anything is set in stone. Would you consider this character a hero, a villain or something in between? Assuming the character's actions save hundreds, maybe, thousands of lives, would you consider his actions justified? What if he fails to stop the attack?
