Sin is an imaginary disease meant to guilt trip you into thinking you need an imaginary cure. In Christianity you hear alot of talk about the term that is called original sin. In the bible the original man and women were called Adam and Eve. And everything was going good until the couple came across a talking snake who told to eat from the tree of the knowledge. But the god in the bible warned them not to eat from there. Since the two had no understanding of reason then how would they know not to listen to the snake who was talking. God said "Because you have done this, Cursed are you above all the livestock and all the wild animals! You will crawl on your belly and you will eat dust all the days of your life." And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel". He kicked them out of the garden of Eden and if you believe this is how we were created, a massive amount of incest followed shortly after. This is called the original sin and their decedents will be guilty of this original sin. So about halfway through this book of fabricated fairy tales out of the blue comes Jesus. A Jewish carpenter who finds out his daddy is the son of God. Which resembles the Greek Mythological Story of Zeus and Hercules. But in a plot twist is secretly his father. And also has a another split personality of being God the spirit. Jesus goes around the middle east with his hippie philosophy and then is killed by the Romans. So this is the part where Christians say he died for our sins. And when you say I don't believe in the bible or any religion in general they make it seem like your being selfish since this made up person died for you. When I was a Christian they would use that that faulty reasoning anytime I would question the doctrine. Also another part of sin is that without Jesus in your heart no matter how good of a person you are you will not get into heaven. So a person who lived selfishly and changed the lives of millions of people will burn in hell and face the worst kind of punishment imaginable. But then a person who might of been a serial killer on his death bed accepts Jesus into his heart and goes to heaven. That why Christianity is not about preaching morality to the masses it about controlling people and making them complacent with their lives. A person can donate their last dollar to a con artist the like of Pat Robertson but still feel what they did is right since in the next life they'll want for nothing. So the next time someone is guilt tripping you into thinking it your fault for what someone before you did just ignore and be responsible for your own actions.
