Think of it this way: a scorpion is venomous and deadly, and often thought to only be looking out for itself. The people who live in the Big House aka the House of the Scorpion are the same way. They are, for the most part, vile people and don't care much for others, only looking out for themselves There is a glowing scorpion in El Patron's house that opens up a tunnel, but only El Patron's DNA can activate it.
Matt later uses that tunnel to help him escape from the Alacrans From 307431 : I learned later alacran means scorpion, so there that's how it symbolize.
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.
