Mr. Aslin, from Newark, Nottinghamshire – who was sentenced to death – said he was beaten and stabbed while being held, prisoner.
Now he has said he will report on the war from his YouTube channel but not take part in the fighting.
Mr Aslin was captured in April while fighting in the south-eastern city of Mariupol. After his release, he revealed he was kept in a small cell with an open window, no toilet facilities, and little food.
He said he was also threatened with death, punched and forced to sing the Russian national anthem.
But returning to Ukraine after such a horrific experience may seem surprising. But Aiden has long accepted the risks.
Ukraine was his home for four years – he still has a deep connection to the country and a drive to play a role in the conflict he feels he understands.
Conflict material on social media attracts a considerable audience. There are many fighters, civilians, and citizen journalists who tell their stories on Instagram, YouTube, or other platforms, bringing us closer than ever to the realities of war.
This is the medium Aiden now intends to use to help shine a light on the continued struggle of his former comrades. He feels he will be able to provide a perspective that perhaps mainstream media outlets cannot.
Aiden is a well-known face in Ukraine by now, which will open some doors, but he also knows it could increase the danger.
For loved ones at home, it is not easy to let him go again, but they stand by his decision.
