There are people that put out fires and there are people that start them. The latter category tends to be divided into a variety of groups. There are the ones that start fires for a particular purpose, such as political or financial gain. There are the arsonists, who start fires to break the law. Finally, there are the ones that start fires because, in theory, there is something fractured about their mental health and stability. Pyromania is often categorized as a form of psychosis that centers around fires, explosions, and virtually anything directly connected to the two. People who start fires because of this condition often lack any other motive for burning things other than a deep psychological "drive" or "need" to do so.
