To narrow it down to just one thing, it’s hard. There is so much wrong with the world we live in. I would have to say, if I had only one choice, I’d say greed. Greed brings out the worst in people. Everything in society revolves around how much money you have, how much you make. It causes people to be money hungry, power hungry. It’s terrible. Hate is also brought on by greed. So without it, we’d have less hate.
