For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against a spiritual wickedness in high places
The inner evil conflict
While certainly not as widely seen as the direct good vs. evil conflict, the concept of “individual vs. self” is often much more compelling to a reader/watcher, especially if it is the protagonist. In both literature and film, it requires well-written character development in order to succeed truly.
Joseph Conrad‘s version of the inner evil conflict, known as the Heart of Darkness, is a human‘s struggle with their own morals and their own battle with their hidden evil. Although first chiefly used in the novel, this improved device was commonly used, as opposed to the old devices used in literature before the turn of the century. It is a conflict that exists outside of literature as well, making it a universal truth of the human condition.
