The Serbians wanted to get Bosnia and attach it to its territory, but Bosnia didn't just had Serbian population, but also Croatian and Muslim populations. The Serbians saw their military superiority over them as a chance to perform an ethnic cleansing, and so they did, attacking innocent civilians and killing thousands of Muslim Bosnians, as well as Croatians.
