I'd never want my kids to go through life trying to conform to anyone else's life. They must work with their own talents, as he has with his manifest gifts, even the ones like good looks, success and wealth that caused him and so many women to participate together in bad behavior, for which he is now having to pay a price. So if not a role model in every area, he can be an object lesson for kids in that no matter how good you are at some things, all that glitters isn't gold and can come back to bite you.
When a powerful influencer affects our kids, parents must teach their kids to differentiate themselves and be their own person answerable to their Lord, not other people. We had an in-law who broke up our family because she didn't like the (totally non-criminal) offenses of her husband's siblings. Rather than teach her kids at home what values she and her husband wanted, she set about burning everyone else's relationships to the ground, deeply distressing her husband's parents. You guessed it: liberal, elementary school teacher, mainstream Sunday School director.
Thank God my husband and I raised our children with our values. But I was merely answering the question if Turmp was a bad role model. By my standards he is.
