Likewise In the book History of the Devil, by Paul Carus, , states that THIS WORLD OF OURS is a world of opposites. There is light and dark, there is heat and cold, there is good and evil, there is God and the Devil.
In the Bible, Genesis 3 we find the account of a being in the form of a serpent (Satan) who deceived Eve, the first woman to disobeys God. Satan is the account of being who is capable of deceiving the whole world and the root of all evil (Revelation 12:9).The Bible makes it clear that each of us is a sinner by nature as well as by choice.

According to Psychology Today, being good is the capability to comprehend with other people, to feel compassion for them, and to put their needs before your own. If needed, sacrificing peoples own well-being for the sake of others. All of the saintly people in human history have these characteristics. Like Mahatma Gandhi and Martin Luther King who risked their own safety and well-being for the goal of gaining equal rights and freedom for Indians and African Americans. These were human beings with an empathy and compassion which sacrifice their own ambitions or dreams. There can be no good without evil because people will make mistakes and be tempted to do evil. Yet they can only be good by voluntarily choosing to be good.

According to the article by Kendra Cherry, human personality is complex and has more than a single component in which in her study which she proposes the three basic components of human personality which are the id, ego, and superego in accordance to Freuds theory. According to Sigmund Freud In his structural theory of personality, personality is composed of three elements. These three elements of personality known as the id, the ego, and the superego work together to create complex human behaviors.
