I believe everyone could benefit by reading the Book of Evil, but unfortunately, what you have done is list 7 truths on why evil is 'good' for lack of better words, and made it an absolute. Evil is as shackling as Good. They both have limitations, and a code of conduct which when followed, imprint upon the person, labeling them so. Your 7 truths list the benefits of following evil, and I am sure someone can list 7 truths of 'good' and why they are 'crucial' to the existance of oneself. You both would then be following the classic archetypes of the eternal debate.
I present to you, and everyone the solution, and the truths for which you seek for with such fervor. I will use your 7 truth analogy, and replace a few words if I may:
1.Evil is simply (a) drive for advancement and greatness (at the cost of others freedom and livelyhood)
2. Cruelty- the application of pain- is the method by which one weeds out the weak minded (and those whose beliefs differ from yours) in order to become stronger (to themselves, and to fullfill the lack of compassion, and spiritual strength that they have thrown away, and thus disuaded the balance of Energy)
3. An (enlightened, not evil) being is one who has eliminated weakness in all its forms: (Spiritual, Mental, and Physical). *Limiting this feat to an 'evil' person, and to no one else simply corrupts any merit to this statement*
4. To strive for strength and personal gain is (instinct). Those who trumpet (natural) values of forgiveness, tolerance, and laxity of discipline, are enemies of strength. *Laxity of discipline is indeed an enemy of strength, but without forgiveness, and tolerance, enlightenment is beyond your grasp. One must encompass the Whole of discipline in order to truly master it*
5. The body can be made stronger in combat, and to strive for personal gain is ( honing one's personal physical ability), therefore engaging in combat with any being (who threatens your personal being, be it mentally, or physically) for the sake of becoming stronger is (noble, and without ignorance)
6. The mind may be made stronger through the (AWAKENING) of conscience(ness). One does this by (knowing thyself, and adhering to the path and practices of the Way)*The statement you put here was absurd, and is detrimental to any type of gain, spiritually, or physically*
7. The spirit may be made stronger by enduring hardships, both self-imposed and externally imposed. *Bravo. Through the use of balance, and by embracing the way of both Good and Evil, we may indeed strengthen our spirits by enduring pain, physically and mentally.*
Indeed, I hope your drive for the truth never leaves your being, but I can only hope your shortsightedness is replaced by the simple understanding of the term absolute. Nothing is absolute except the Whole of things, and the plan that nature sets forth for us. Life is a chaotically simple enigma of questions and more questions. Of the multitudes of men and women that have existed, at one point, they have each seriously questioned themselves, what they are, and where we are going. Only a minute fraction of those recieve the ability to let go of ideals that imbed themselves deep into one's soul. Words, and terms themselves are limiting, and therefore have no place in one who is seeking enlightenment.
One who seeks for perfection in 'Good' or 'Light' will only find half the answer. One who seeks likewise in 'Evil' will find half as well. Without the two made Whole, you might as well possess a dead goblin who fought bravely for his pickaxe, but died for the cause of evil, or good. You will spend an eternity searching for something that could be yours if you let go, better yet, EMBRACE the half of you that you seek to eradicate.
Luck to you on your path, and should you wish to arrange a personal discussion, I welcome all forms of intelligence to further strengthen my grip on Truth.
