Conscience means that the inner sense of what is right or wrong in one’s conduct or motives, impelling one toward right action: to follow the dictates of conscience or it means the complex of ethical and moral principles that controls or inhibits the actions or thoughts of an individual. Most people can’t act as their conscience tells them so. Because conscience cannot give them an order. All it can do is to tell them not to do what they wanted to do. Especially if their motives can harm a person, it is up to them if they are going to follow it or not. Their will allows to do or not. In other words, conscience may be enslaved by their will, conscientiousness. This lets us know why the world is not a good place to live peacefully, there are many unexplainable reasons why God of love has created such a chaotic universe.
I believe that God did not make the world. In contrary, I suppose God and Satan mould this universe. Because there are two things, good or evil in our mind and all things.
