Often when children go astray it is because of a lifetime of parents and relatives laughing off inappropriate behavior. "Watch thing, he is so cute when he hits his brother." "Look at my little man, 6 years old and he has his first tatoo." "Church is boring son, let's go sit in the car." "Go sneak me a cookie and don't let your mother catch you."
Sometimes it is from watching parents repeatedly do something that crosses the line. "No officer, I thought I was going the speed limit." "Put your snacks into your coat and walk in the theater holding them so they don't fall. No one will ever know." "Go ask them for another and tell them you didn't get the first one."
Recently I was at a meeting where a woman said that entering the country illegally is no bigger than driving 5 miles over the speed limit. It was technically probably not right but the greater injustice would be if we didn't let in anyone who wanted to be here. Besides, it is only illegal if you get caught. Maybe it is time to go back to read D&C 134.
