By 1905, Russia was not in a good place. They had been humiliated by their defeat in the Russo-Japanese War at the hands of Japan's "inferior" soldiers, and the populace was angry, hungry, and underpaid. One of the riots in 1905 was Bloody Sunday, which was organized by Father Gapon (who may have been a two-faced agent). Even though the demonstration was nonviolent, it was put an end by a powerful military response that, while not specifically planned by the Tsar, did not benefit him.
Since the protest had been a peaceful movement, the armed forces' open brutality in their responses was harshly denounced. It most likely enraged the demonstrators even more and escalated their animosity toward the Tsar, who would be compelled to create the Duma (which would end up being just as useless as himself given the placement of pro-Tsarist ministers).
In conclusion, it hurt the Tsar's prestige but didn't threaten to bring about a revolution in the nation (unlike his decision to assume Commander-in-Chief during WW2).
Thank you,
