Hi jaywill,
You miss the point. The point of the theory of Evolution is not whether it is comforting or morally uplifting. It is not even whether Eric Kliebold understood it correctly or not.
Evolution is supported by the evidence. It is supported by all the available evidence and it is not contradicted by any evidence.
Evolution is true. There is no other point. The ToE is not expected to contain moral lessons or values, nor should it.
The same cannot be said of religion, which should have moral lessons and values. The criticism that religions and religious practitioners only have a patchy track record in this regard seems fair to me.
