This statement leads me to believe you have very little knowledge of the real world. Nearly all species place an innate value on their members which exceeds that placed on members outside that species. When dogs (or blue jays, or elk) fight, it is never intentionally to the death. Why should humans be any different? Even pre-Christian and non-Christian people had to be taught to kill other humans to make them effective soldiers. Of course, you always have the occasional person who loves to kill (humans appear to be the only critters thus encumbered -- which makes certain arguments about "made in the image of God"), so he'll find any convenient excuse to ply his hobby without being removed by his fellow man.
Nor does it try to do so. You are still arguing against your own strawman.
We are just seen as more highly evolved forms from an original source that happened by chance.
Not "highly" - highly is a meaningless adjective in this context. However, we are more specialized than other hominids towards a larger brain, unimpeded voice box, and bipedal stance.
There is no foundation, other than human opinion, for any kind of moral judgment and that opinion could vary from place to place and we legitimately would have no foundatin for stating it is wrong.
Like gravity or quantum mechanics, the theory evolution makes no moral judgements. Same strawman.
In the Darwinist world, one can NOT say with a rational basis that Bin Laden was evil. One can say I don't like what he did, but his majority rule may say it was perfectly okay.
On the contrary, as Junior has pointed out several times, both the individual instinct and the cultural basis for survival, reproduction, and the protection of one's children, impose such judgements. And for clearly rational and easily understandable reasons.
Saying that murderers like John Wayne Gacy let "demons" control their actions absolves them of direct personal responsibility for their actions. And, personally speaking, how is it different than saying "the Norms controlled their fates" or "the Elf-Queen made them do it", or even "evil space aliens from Zarg contolled them like sock-puppets".
