You are wrong in the most fundamental way.

The fact is, any belief system has tremendous fundamental impacts on behavior and values.

Honestly, this is such a basic concept that it would take much time to explain it to you, but I'll attempt to make it clear in this way.

If I were to believe in evolution, then my killing of another person to make myself rich is only the process of the survival of the fittest in action. If I were an evolutionists, I would not see anything wrong with this behavior as it happens in nature all the time. I would also believe that attempt to inhibit this behavior would only be suppressing the natural processes that results in human evolution and would be detrimental for the long-term survival of the "species" (why preserve the weak?).

Evolution is the official religion of secular humanism and satanism, and ultimately communism. Most socialistic philosophies derive from evolution. This is a fascinating study in and of itself with profound implications.

If, with some thought, you are still unable to make this fundamental connection between a faith in evolution and behavior, please let me know and I'll post some material to help you.
