It's not condescending, its against military ethics to parade a pow. I dont recall in the previous wars India or Pakistan doing this , and everyone knows India has had quite a few Pakistani pows in its custody. I criticize Indian behaviour because I want to see a better India but in this case the Pakistani behavior was dishonorable. It reminded me of the Pakistani hockey players behavior after their win. India has been overwhelmingly defeating Pakistan in cricket and hockey in the last couple of decades, but the players were always very professional.
The narrative in Pakistan needs to change, it unfortunately fuels reactions in India too and makes mature behavior rarer.
