He really couldn't. We think as we like. We have not been endocrinated though I have friends that have been. It is just not that easy.
I don't believe that he alone is responsible for his behavior as a young teen. I am okay if people don't agree with me but I believe he had a lot of help and influence.
When you repress natural urges in a boy and tell him he is bad or wrong or going to hell you make him secret things.
It is learned behavior as a child.
He had an affair and that is sad and wrong. But I still believe his upbringing all the secrets he had to hold or be scolded or damned or whatever... played a huge part in his malfunctions.
Yes. I actually think it is unlikely that he would've molested little girls and cheated if not for his background. But you're missing a huge aspect of that background. It's not just about being repressed sexually and having every act and thought controlled. Josh was raised in crazy-making dichotomous culture that is at once extremely repressive of any sexuality outside hetero marriage, including masturbation, looking with any kind of lust at anyone, discussing sex or the body with anyone your own age, seeing anyone besides yourself and babies naked, and even thinking any type of sexual thought when not married (young women are instructed not to even dream about romance or a future mate but to instead be a satsified stay at home daughter until God suddenly drops a mate into her lap - -through a mating arranged by her father), but which is also super, incredibly sex obsessed.
This is culture is hyper aware and obsessed with sex. Temptation, "defrauding" women, "unnatural" sex (gays), and the joys and constant discussion, insinuations and even demonstrations of hetero married sexuality (i.e. The Duggars constantly making out in front of their kids and referencing what they do in the bedroom "hey hey hey!" and "you don't get to do this until your married!") are major obsessive focuses of the culture.
And that's an incredible toxic brew- obsession and repression.
But the key element that when added makes for an even more incredibly toxic environment that virtually guarantees a high level of sexual abuse and dysfunction at all levels is the gender stratification. And the utter patriarchal domination. Women must submit to men. All are taught that the body cannot be trusted, that women and children's bodies are not their own, that men have a direct line from God and are thus "headships" of their wives and children, including adult unmarried daughters and that women are utterly at fault when their headship does something wrong including adultery, child abuse, sexual molestation, gay sex romps and domestic violence.
So imagine a boy being raised in that? Being inundated with sex, told he must repress his sexuality but also told that men control women and children's bodies and sexuality and are above women.
It certainly doesn't make me feel Josh is not to blame. Despite the above, he had choice. I think he is a selfish creep and has definite predatory leanings that he acted on as a teen. But I am agreeing with Scarlett that the culture and the parents bear some of the blame. The incidences of this kind of behavior are higher in cultures like this.
