@existential potential,
It's impossible to know one's religious beliefs and how it impacts their life. Since there are many religions in the world, and many so-called adherents, they seem externally to devote some of their lifestyle to their religious belief.
Many go to their place of worship, and pray at different times of the day.
However, out of these masses are the very criminals that commit the most heinous of crimes. The US is no exception; over one-third of the US population declare themselves to be members of the biggest Christian faith that includes Catholics or some protestant religion. I've read some years ago that over 80% of Americans believe in one religion or another.
The relationship between the truly religious and someone who attends church because it's expected from family or friends are difficult to determine. When is an individual truly religious?
I believe they are the same group from which crimes are committed.
