That depends on how you define morality. Even secularly we are influenced by the Judeo-Christian mindset, although we find non-religious reasons to find justification for why we think we are right. The human-sacrificing Aztecs did not lack morality nor were they a backward people, they simply had a different moral code.
I don't agree that "secularly we are influenced by the Judeo-Christian mindset" actually. LAWS in the Western world have a nasty habit of being, but otherwise...
Nor do I for one moment suggest that the Aztecs lacked morality. That is my point, in a way. No religion can define it, it is in ourselves. BUT - if the Aztecs had not had a god to sacrifice humans to, they might have thought about what they were doing and not killed people in the way that they did. We all find reasons - religious or not - to justify the things we do. And we shouldn't actually; we should be able to argue them in terms of the actual reason we did them.
I stole because my family were starving. Fair cop. Honest reasoning.
I cut your hands off for stealing because god says that is what to do - not fair cop. No thought given to it at all.
I cut your hands off for stealing because stealing is wrong in my eyes - middling fair cop. At least you admit it is YOUR eyes.
I cut your hands off for stealing my CDs because they were mine and I loved them - fair cop. Not nice, but honest and true to one's principles.
(I will let you know how that all pans out when my mother asks me WHY I told my sister not to help her any more... I am certain I am doing the right thing - and I defy anyone to find any reason related to any god that says so. )
