The only difference between right and wrong is what you as a person perceives. What is wrong for one person is right for another. What is right for one person is wrong for another. There is nothing in the world that EVERYONE agrees with or disagrees with. Many would say what is right is doing what is moral and acceptable. Terrorist thought it was acceptable bomb New York. Again, it is all about what you have been told to believe, and thus what you perceive...Literally belief is power, and belief itself can change the physiological structure of your brain. What is right and wrong is different for every person. Ask a Nazi during World War II and what Hitler was doing was right, Ask an American during this time and what he was doing was wrong. So which is it? The answer is both and neither, it depends on who you ask!!
It upsets me greatly the amount of religious bigotry in the world, the one thing you should attempt to learn in your life is that the will never be a time when everyone agrees. Right and wrong are not objective, not absolute, they cant be, its logically impossible. They are simply a comparison, with out one the other is not possible. If everything were good, nothing would be because something is only good to you because something else is evil. Its based on what you were told to believe. No one is absolutely right and no one is absolutely wrong about anything.
