Also, they have no way to learn from mistakes because a single mistake as a teen or young adult can mean an entire lifetime of consequences even if little to no harm was done. If you only do things out of fear without knowing the reason they're bad, then you never learn why your impulses might be bad and eventually you'll do something with much more severe consequences. This is why many kids raised in strict environments, like religion, stereotypically end up getting into so much trouble later in life. They have no experience with the real consequences, only the extreme, fabricated ones.
