A prevailing truth is that nothing possesses the ability to originate from its opposite or to exist simultaneously in the same entity as its opposite. Life and death cannot survive together, ignorance cannot arise from knowledge. Yet good and evil, commonly considered antitheses, have the capacity to exist in each other's presence. Furthermore, the two ideas exist in all actions and in human beings themselves. Because of this coexistence, good and evil simply cannot occupy absolute definitions, but must rather be defined relative to each other. Therefore, as made clear by Gardner's Grendel, Shakespeare's Richard III, and Moore and Lloyd's V for Vendetta, all people must experience a moral struggle due to misunderstanding of the notions of good and evil. However, not only this feature of the two ideas, but also the arrogance of human beings is a contributing factor to the struggle for morality since it is human nature to do what is in one's own self-interest. In Genesis, Adam and Eve, the first parents, act both for good and for evil. In the Bible, good is defined as being pious and submissive to God and his holiness, which Adam and Eve eagerly do. Yet they eat the fruit of the tree of the knowledge of good and evil, of which God forbids them to eat. Although Adam and Eve are supposedly ethical people, their actions opposed God's ideals of good. Conveying the same interconnection between good and evil, Grendel's Shaper tells seemingly righteous stories of the Danes' exploits, but at the same time tells tragic stories and of death. As Gardner explains, “he built this hall with the power of his songs: he created with casual words his grave mor(t)ality” (Gardner 47). It suggests that on the surface the word of the Shaper... in the center of the card... new presence of the two. Accordingly, moral struggle is not only about the internal debate between right and wrong, but also refers to the effort to resist arrogance. As a result of this moral striving arising from both ambiguity about right and wrong and the tendency to act in favor of oneself, the concept indirectly projects the thought that struggle is beneficial and perhaps even imperative. As Williams explains, those who live with a clear “balance of dos and don'ts… wonder whether a life lived in accordance with this code can be seen as full, mature and abundant” (Williams). Living such a categorical and unconditional life is simply not satisfying and inhibits one's ability to experience all that life offers. To lead a full and interesting life, uncertainty must prevail, as it exists in the ideas of good and evil.
