1] The inexplicable obsession with fire, burning and any flamable objects.
2] The irresistable urge to watch fire or to lite one.
3] The disregard of other's lives, possessions and feelings when they conflict with the starting of a fire.
4] Feelings of lust are displayed when watching, liting or simply being around fire.
5] The reasons for starting the fire are not for revenge, property damage, the desire to start anew, light or entertainment - but an indescribable feeling that comes from simply watching flames - one that the pyromaniac cannot control.
Pyromania, what is slowly taking over the world with the beginning of pyromaniacs.
