The increasing of disbelief in God has resulted chaos. I have my reasons for saying this.
Why you should afraid of death if you will only gone for a long sleep? So, atheist is not afraid of death. Then, lets have some fun. Do as you like. Even if you die on your journey, there's nothing to regret. If you're a killer, you'll be send on a long sleep as a punishment. If you're a gangster, you'll be extra of it because you have nothing to afraid of. You will only gone for a long sleep. After all of our doing, no matter how evil you're, you will only be sleep peacefully like other people do.
Why should we afraid of being annoying to others and to hurt others if we will only go for a long sleep after we died like many people do? Why should we follow the rule created by mankind if we can break it? We have nothing to lose. We can satisfy our wild nature and enjoy life "fully" by not losing anything.
