I think any ethical scientist would agree that science without morality is madness. The Church is one source of morality.
Yes science needs ethics but are you ignoring the other sources of morality. Are you suggesting that you have to be religious to be moral? Yes the church is one source of morality, where it draws it's morals from though have no solid backing and again it all comes down to that big book of facts. Morality can just as easily be obtained from a law maker for example. I'm not religious and I know what is wrong or right. it's human instinct, murdering is wrong, period.
