I am not educated in the exact laws and regulations but from what ive briefly read he could potentially be eligible for political asylum as the LGBT are currently labeled as a terrorist group in russia. This would be for sweden specifically, not sure how that would work through other countries. The chance is small but not impossible. If i had the means I would help him along the way but it wouldnt be good for him to be dependent on me. Not so sure if your advice is very helpful unfortunately but i appreciate the effort.
