Negative pointed you to some deep water. What I mean by that is in your search for the answer to your exact question delving into said info will just leave you with more questions.
A too rich supply of information will always breed more questions. But to the point "How can it be good"?


The first and foremost reason is it puts great value on human life and it's condition.Without it you could reason that a germ,maggot,buzzard or bear is equal with a man in terms of "right of existence". There are poeple who reject such a position and they are the ones who hug trees and kill unborn babies in the womb.


Secondly it also stands in stark contrast to primitive man and his worshiping of the forces of nature. Primitive man didn't understand forces like earthquakes,volcanos.hurricanes and tidal waves.Therefore he personified them in a attempt to negotiate with said forces. Hence we had sacrifices and self-scarification and such.When "enlightenment" surfaced we began to understand the forces we used to worship and we began to worship ourselves.
The exitentailistic statement "God is dead" was the peak of man's self- proclaimed diety.
Biblical absolutes were overthrown in favor of relativism.It is the culmination of what the serpent told eve in the garden"when you eat of the tree of knowledge you shall be as God"
Christian's view the moment as an evil one but some see it as man(heh or WOman) breaking the shackles of a despotic diety who wanted to keep man in an ignorant state so he(God) could be worshiped.
