The problem was that Justinian contributed to the fall of the Byzantine Empire by spreading its borders too far, to maintain control got harder which caused many civil revolts and left the empire unguarded for attacks. 

Justinian also wanted to build new structures like churches, aqueducts, roads, and others, but to do so he needed money which caused him to raise taxes and lose the confidence of the population.
