I don't think he could be classified as a serial arsonist but when he was younger I believe he like to start fires just for fun. Of course fire-starting is one of the warning signs of a serial killer in the making This does not mean that every child that plays with matches will grow up to be a killer. In fact the odds would be very small.
But when a child starts fires, tortures animals, ect I would think these would be taken together as a red flag.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
