That wasn't a constant thing though, and China despite being unified had far more bloody civil wars with more people dead.
But sure Europe being fragmented did lead to more wars, which is bad. On the other hand those wars mean European military technology advanced quicker, and the existence of multiple political units meant that different ideas about religion, science and society was far more difficult to suppress than in a unified China.
The price China paid for its unity was a far more oppressive regime. To keep such a huge empire from falling apart a lot more state power had to be exercised. At the time of the 30 years war the average Europe was generally a lot freer.
One could say there was a tradeoff. Europe "accepted" more violence for more freedom. China "accepted" more peace for less freedom. What you prefer depends on your values and ideological beliefs.
