That's because they have no values. They are selfish. All they care about is themselves. There should be no responsibility for action unless the action is taken twards them. The majority of them believe nothing, they are empty headed. Often giving insult to those that do believe in a higher power. They criticize and often times wish death on those that are in disagreement with them. They blame all the issues of the world on a God that they don't believe in. It's not about morals, it's about what they want. You can compare them to a 2yr old in a candy store.
