Conscientiousness is taught and learned. You weren't born with your current conception of what it means to be a conscientious member of society, you learned it explicitly and through osmosis. "Nobody with an ounce of decency" is an unnecessarily loaded way to refer to people who, frankly, are who they are through no real fault of their own.
"are who they are through no real fault of their own"
This is the ultimate cultural relativism rubbish, no offence, but people make their own decisions in life. It's this kind of reasoning that some try to use to absolve murderers and thugs for their actions.
Surely on some level we're all the result of our upbringing, but we also have to take responsibility for what we are at some point.
