During a period of military service in the Austro-Hungarian Army in Vienna, he recognized that his true interest was in being an artist. He began his training in the craft under Anton Runggaldier (known as "Tone da Passua") and then became an assistant in the studio of Franz Tavella. His own works ranged across a number of religious themes, and were mostly created for the various churches and cathedrals of the Grand Duchy of Baden and the Kingdom of Württemberg.
He created a famous set of the Stations of the Cross for the Church of Saint Ann in Silesia.
Moroder re-entered military service when World War I broke out. Stationed at a base in Radlow in Austrian Galicia, he was there when the position was overrun by enemy forces.
He, along with many of his comrades, was bayonetted to death, dying at the age of 37. His body was buried there.
