I have my ranking as such:

1-Money 2-Political 3-Revenge 4-Boredom 5-Recognition 6-Entertainment & 7-Multiple.  Number one is always going to be my main one to go with because our current worlds root of all evil is forever going to be money. When its gone we lose all morals and will do whatever it is that we need to to require it especially if we know we have the skills to achieve it all so easily. I see a lot of the things that we have today was brought to us through crime and horrible doings especially when it comes to politics because that plays a big role in most folks decisions as well. I but Entertainment as last because i don’t see much people trying do commit such serious crimes just because they’re bored.
