Also World war I was wanted by everyone. SIMPLY EVERYONE wanted this war - Poles, Russians, Germans, French, Italians, Spanish, hungarians... So this war just had to come. I doubt ottomans empire existing or not would change it. More likely it would just make it worse war, aspecialy as germany could ally with ottomans, which would be devasting for europe(aspecialy due the fact turks did participated in both world wars, and in both they swithed sides, when they felt it was going to bring them profit).
But none war is good thing, as war mean killing people, and killing people is bad. But it does not mean you shouldn't defend yourself.
