Although 'free' is, I suppose relative: he's currently 'in hiding', and, as an Independent article notes:
Prior to his departure, he spoke of how his relief was mixed with deep regret at knowing he was unlikely to see his family or country again.
Still, considering he was first sentenced to death and then had his sentence commuted to a lengthy term of imprisonment, this is, of course, good news.
Wherever you are, Mr. Kambaksh, we wish you well. And hope that you may one day return to a free Afghanistan.
