Universal meaning and value of life for all intelligent living beings
Life is relatively short and fatally limited. The universal meaning and value life has for intelligent living beings, is first the possibility to enjoy their own lifetime physically and intellectually, which means meaningful to themselves, second is being useful to others physically and intellectually, which means valuable. If any life is both meaningful and valuable, it's a perfect life. Otherwise it's imperfect. All these living beings deserve to live. The evolutionary scale ends with degenerates like parasites, predators and their clones, who's life is meaningless and useless, also harmful to other meaningful and valuable living beings. The degenerates, who are the last in the evolutionary scale deserve to die, because meaningless to themselves, valueless and harmful to others.
There are six types of living beings in universe:
A - 0 (Alfa): Perfect life, which is both meaningful and valuable. Normal.
B - 1 (Beta): Imperfect life, which is only valuable, but meaningless. Normal.
B - 2 (Beta): Imperfect life, which is only meaningful, but valueless. Normal.
Ω - 1 (Omega): Degenerated life, meaningless, valueless, also harmful. Parasite.
Ω - 2 (Omega): Degenerated life, meaningless, valueless, also harmful. Predator.
Ω - 3 (Omega) Degenerated life, meaningless, valueless, also harmful. Clones.
Universal meaning and value of life based on defending normality
The reason to live is related to the quality of life. The quality of life is correlated directly to the quality of life in the natural habitat. When the quality of life is perfect, the meaning of life is obvious. When the the quality of life fluctuates from normal to abnormal, but the suffering is tolerable because still inferior to pleasure, the meaning of life is still clear, because of hope that it can be realistically improved by intellectual and physical endeavor for creating a better to perfect society.
When the quality of life is below normal so low, that the suffering is intolerable because superior to pleasure, it makes impossible to hope to be able to better the natural habitat, therefore the meaning of life disappears for all normal intelligent living beings till they become all delusional parasites or degenerated predators, unless there is still any hope, because hope dies last. In a state of balance between very low meaning of life and hope, living beings are capable of heroic actions.
The only reason for natural habitat to become incompatible with providing the meaning of life, is only when delusional parasites and degenerated predators manage to infiltrate society and become the elite to control over it. Because parasites and degenerates cannot understand the meaning of life, their actions start slowly but surely to eliminate all the fundamentals of it trough corruption and degradation, at the end finally achieving the total collapse of the meaning of life for everybody else.
The only way to protect the natural habitat of normal intelligent living beings is becoming able to study and also categorize, detect, contain, reverse, eliminate and prevent parasites and degenerates of any kid from infiltrating society, using kinds by patterns of stages, like causes, beginning, development, resolution, completion, effects and side effects of their activity. In case it's too late, and they already have control over society, the only meaning of life is to become divergent and insurgent against them. If normal living beings have still not become parasites or predators themselves, they have nothing to lose.
Intellectual actions to beat enemy psychologically and physical actions to beat enemy physically.
