He's trying to justify his actions to himself - he's not in the right state of mind. He's trying to convince himself they had it coming.
He was like any other human being: a man clouded by both racism and opportunism. But the fact is that unlike Ben-Gurion, Aflaq and his goons wouldn't have lost an ounce of sleep over the annihilation of the enemy.
