That second part is of direct concern to me, and to many other people. These decisions include whether to tell the truth or lie, whether to work for the common good or grab whatever you can get, whether honor and honesty are more important to the person than status and finding an easy way toward personal goals. Persons who believe in science have substituted Newton's laws and the periodic table for religious/spiritual principles, which just doesn't work. It seemingly gives them a framework that allows them freedom from the encumbrances of morals or ethics. But those encumbrances are part of being human, and without them these persons are just shits.
What's most interesting is that it's usually the most religious people who buy into the Republican Party's ideology, which includes "grabbing whatever you can get" and espousing Ayn Rand-style objectivist philosophy.
By contrast, the irreligious people are much more liable to vote for politicians who push social welfare programs ("working for the common good").
So the idea of religion giving people any kind of decent morals or ethics is blatantly false.
