Evil is distortion of Energy Law, aka God; simple eviling, energy-veiling, is like asking for a second serving if one's better angel is urging "portion control." As eviling cuts one's self from God, Energy, the hollowness of the evil Mr. Hyde or early Scrooge is a kind of social-ist or plutocratic (great whore/business personalities in John's "Revelation" of human psychology in conflict with the Divine) becoming a step-by-step choice to either be just, true, and merciful, and return as prodigal Son to heavenly Father, or no. The hollow men or men without chests motif is the evil-doer who is using up her spiritual reserves, and if there is not a choice toward good, Childlike kindness, forgiveness, and the like--and a reconnection to God's Light and Energy--then the eviling becomes more wicked, more manipulative, more "talking serpent." Thus if such devolution occurs, a kind of vampirism preying upon the energy of the good person typically plotly occurs. If the subconscious of a John Milton powers a subtext in "Paradise Lost" of "the snake has all the lines," the author's focus or intention has subtly shifted or altered. In other words, the character of the author, at various levels, may lead to the "dish running away with the spoon," as in "Lolita (or Lilith) running away with the 'spoon,'" etc. In reality, there's Truth of Goodness, and then relative good and evil, and the good soul character is like the good Capt. Kirk vs "evil twin"--the "twin motif."
