It was a good reason. As good of a reason as one could have, really, though killing was never justified in Oliver's mind. But he was still stunned and confused and angry at what had happened, and now he was angry that Asch was angry, even if Oliver did understand somewhat. "Then say that!" he yelled back. "Just...god, why did it have to be here!?"

If he'd been on the Plane, this was the point at which he would have started to yell his frustration at the sky, but his pride wouldn't have it, nor could he risk it here--particularly if Asch's enemies were nearby. So he turned away instead, starting rather aimlessly to stalk off in a random direction. He wasn't thinking straight; he was just upset and angry. But his feelings for his friend were eating at him, too, struggling against his desire to get away. He stopped, turning back to Asch. "Look...was that all of them? Are you safe here?"
