William II's mood was quite bad, primarily because, in his view, Germany was not prepared for war, and the simultaneous declarations of war by Russia, France, and the United Kingdom were beyond his expectations.
Although William II often spoke of war, his attitude toward it was actually very cautious.
Otherwise, when Russia began mobilizing, William II would not have admonished the Russian government to stop, essentially hoping to avoid a military conflict with Germany.
Though war between Germany and Russia was inevitable, William II had no intention of starting it now.
The true culprit behind this irrevocable situation was actually William II himself; the Austria-Hungary war party led by Conrad was unafraid to declare war on Russia due to William II's guarantees.
