> But you have no evidence that your ancestor's faith worked well.

I am, to a certain degree, that evidence. (Edit: this holds true to some degree even if you look at it from a purely techical POV which makes me smile : )

> Probably the opposite, if you look at any conflicts they were involved in, or what social advances were blocked.

This is meaningless unless you also take into account the advances brought forward because of it.

And, FWIW, you have to cast your net wide and far to find anything real horrific.

This is not to say we are better people than other, but trying to say our faith made us worse than the alternative (warrior tribes as they existed some hundred years ago) seems very wrong.

warrior tribes?
