what is your opinion of the ending of the story-'the sniper'?do you think violence is ever justified?

I think the ending really speaks to the futility of war. After the sniper shoots an enemy soldier, he discovers he has just killed his brother. The sniper's emotional detachment throughout the story, coupled with this startling ending, allows O'Flaherty to indirectly address the way in which the Irish civil war led to the disunity of Irish society.
