In spite of the pointless debate here on who started it (100 years ago) there were no real good guys in that war, Germany surrendered when German citizens turned against the war, which Wilson's 14 points helped stimulate.
After surrender France and England threw away the 14 points and proceeded to humiliate and cripple Germany for pure revenge which was proven to be very short sighted.
A classic anti-war movie is Paths of Glory which gives a taste as to how little French and German lives were considered worth in WWI.
Germany surrendered and signed the Armistice only when the Allied blockade had starved the country into submission.
Helped of course by the fact that the Germans had sharply denuded their agricultural sector by taking men off to the fronts.
