That very much depends on whether he knew the girl was being trafficked (as opposed to pimped) by Epstein. Without this case, how many people on here knew beforehand that in the USA they have a law about taking anyone under 18 across state lines for immoral purposes? Equally, in some US states the age of consent is as low as 14.
Don't get me wrong, I think P Andrew is very sleazy and shady, but how many entitled men of that age think that if a girl of legal age in this country came on to them in a bar, their first thought would be "have they been trafficked?".
There are plenty of older men, older than Andrew, with comparatively much younger wives. Examples you may have heard of include Donald Trump, Richard Gere, Bernie Ecclestone (F1 former head), Mel Gibson, Patrick Stewart and many many others.
He was a stupid, arrogant man who probably genuinely believed he was still the Falklands War hero and that his title of Prince would mean young women fell at his feet. He was even more stupid not just saying up front "What - she was trafficked? Heavens I didn't know that; just knew she was over 16 so "legal" in the UK".
