Diagnosed by the Audience: Polza already seemed disturbed and unstable before he discovered the blast. He's extremely anti-social, and he routinely abuses booze and drugs. It's briefly mentioned that he'd already been arrested several times prior to the events of the story, with the charges ranging from indecency and drunkenness to assault, the specifics of which are never detailed. In spite of all that, Polza is remarkably lucid in recounting his life story. This leads the detectives interrogating him to doubt that he's as "crazy" as he's letting on.
1997 film
Complete Monster: Omado Kallal is a terrorist notorious for killing his hostages. Rigging Atlanta with numerous bombs in time for the Olympics, Omado takes a swim team hostage after killing most of the personnel near the pool, executing several girls on camera to show he's serious. Detonating one bomb to prove his point, Omado plots to kill all his hostages and level a huge chunk of Atlanta, even tying the hero's wife to the bombs so he will die knowing he failed to save her.
