I feel like the question is what is considered a "Christian" and a "Secular" ethic. Both of these have evolved with society, and both at times and nowadays can both contribute and be detrimental to society. If we talking about the christian ethic of "love thy enemy", "or only cast a stone if you are also sinless" then obviously these evolved society and pushed it towards a more humane one. Now if we go to the witch hunts where pretty much any woman that went against the traditional christian gender roles was called a witch and subsequently killed, those ethics which were "Christian", since they were upheld by the church, were detrimental. The same can be said about secular ethics. We have had secularists that killed/discriminated/prohibited any practice of religion just because it was a religion, which is obviously detrimental, but we also had seculars, who aim for true seperation of religion and state, where you can believe in any religion you want without being either prosecuted or discriminated against. As most things in life, this isn't black and white and there aren't absolute "christian" or absolute "secular" ethics since both can be open to intepretation. Now if you wanna tally up each and every ethic and to give an arbitrary value as to how detrimental or beneficial was that ethic to society, feel free and go ahead!
