You know it is true - however - Here is something from Religion Facts.
Christian Doctrines of Hell - ReligionFacts
"According to a 2004 Gallup Poll, 70% of Americans believe in hell. Belief in hell is highest among regular churchgoers: 92% of those who attend church weekly believe in hell, as do 74% of those who attend nearly weekly.
In Christian theology, hell is the place or state into which unrepentant sinners pass after this life. Hell is generally thought to be eternal, and to include both punishment (poena sensus) and separation from God (poena damni)."
"Hell was a strong incentive to lead a righteous life in the early church."
That is quite a psychological indoctrination of a nation!
