The lives of two child stars

I incidentally had the opportunity recently to compare the lives of two child stars, Ricky Nelson and Donny Osmond. Apparently Ozzie Nelson was very strict, authoritarian and controlling. This seems to have resulted in Ricky becoming quite libertine when it came to sex and drugs."Nelson had a tremendous sexual appetite and a casual attitude toward sex, once estimating he had had sex with thousands of women."

Contrast Donny Osmond, who is quoted as saying:

Donny: “I married as a virgin. I really did [laughing]. And, I’m proud of it. It was difficult. Boy! let me tell you it was difficult! The hormones were raging…”
 Piers: “Do you wish you’d just piled in back then, Donny?”
 Donny: “I’m glad I withheld. I really am.”

Hilary White says in the same article,

I think Donny Osmond, with his whole family, represented something more than just silly teeny-bopper pop songs. They were sold as the “clean” pop act of their time, happy, innocent and cheerful. They made their name not only as a talented family act, but as one dedicated to the old fashioned religious-based virtues that had been hugely popular since the end of World War II. They were, in fact, the living embodiment of an innocent enjoyment of youth and, yes, I’ll say it, romantic love, that itself turned to “industry poison” at exactly that historical moment.

I think it is intriguing to think about why morality "takes" for some children, and not for others.  I have no wisdom on the matter at all.
