Excuse me???
He didn't just make an 'error of judgement'. That would be, for example sleeping with a girl he picked up in a club, who has lied about her age. Or dating a girl a few years younger.
Also you've got your facts wrong.
Not only did he knowingly groom a child - he discovered her real age, and still continued.
He hopped on a plane to another country.
Plied said child with alcohol.
Raped her multiple times over the course of 2 days.
Refused to stop despite expressions of physical pain from his victim. You consider this non-violent?
How much more violent did he have to be for you to consider it an, erm, 'sadistic sexual assault'? You want him to have beaten her up too?
BTW, I agree that even paedophilies once released should have some sort of life. After all they to feed themselves too and presumably need some sort of job for that. Social life, marriage, well, if it's known and people still choose to associate with them, nothing anybody can do.
But to represent his country?
Nope.
