IMO, the dark force in nature, was explained in depth by Thomas Hobbes in his 1681 book Leviathan as Man's "state of nature": every man at war with ever other man.
Here is a link to a PDF of that book that is posted in the SIN library: https://www.satanicinternationalnetwork.com/social/forum/topic/238
Although I like the symbolism in that book I don't see nature asking the good or evil question before doing anything. Then again the human nature is different to nature it's self so I do not find any conflicts even if the point of view was a shaped by perspective.
Once ingrained with the idea of good and evil a person may try to distance themselves through altruism but the conscious act in doing so will distance it's self from a nature. In the same way a stage magician can pass of a trick as magic yet will always know the twist they played.
Now if a person wanted to really strip away realities and find the nature of things then I would say look to the real applications of the words good and evil and find why they are there to start with in religious and social based ideas.
I feel great after the situation passes by , and it's over.There's the answer to your 'why'.
I still Have difficulty with how an individual can risk their life to help another stranger in need. Any ideas anyone?
Dimitri covered a couple of reasons but some of the reasons many don't think of are the adrenaline rush or the simple challenge factor. People climb mountains just because there are there and a challenge and some do this for the same reason.
I guess there are also some elements of martyrdom and/or the notion of one's life having a purpose beyond living.
the Sumerian Tiamat represents the destructive.
I don't see how anything described as a sea serpent or a dragon does not have a destructive face ...
If you are unable to remove the emotional attachment to your views when engaged in an argument, you'll miss all the points presented by your opposition.
For example:
Dimitri,
What is your pansy-ass Atheist view on collective morality. Where does it come from? Don't give me that shit about morality being codified by nature. Evolutionary science won't breast feed you that one.
(Let's see if he responds emotionally, ignoring the substance, or sees through it and comes up with a comprehensive response. Mean-spirited or not)
