He certainly seems a creep but I can't help but feel it is ridiculous that in half of Europe (including France, Germany and Italy) it wouldn't have been against the law, but over here because of one years difference, the guy could see 10 years in jail and have his life destroyed.
Conversely there are some countries where the age of consent is 17 - does that mean that all the same 16 year old English girls who are legally "of age" would be traumatised by sexual encounters with a bloke in his 20s if it happened over there?
I highly doubt the girl is entirely innocent in all this either, as other posters have alluded to, 15 year olds are having sexual contact with 'adults' every day.
Anyway as I originally said, the guy is a creep and he knows the law in the country he resides in, and that he was breaking it. But really, we aren't talking about a 6 year old here, nor are we talking about full blown sex even. I don't think the punishment fits the crime, if we are going by the judges estimations.
