Imperial Russia was no more brutal, and in some respects less, than the British Empire. Compared to the French Empire, the Dutch Empire, the Portuguese Empire or especially the Belgian Empire, which was vicious and purely profit-driven (compare the former French, English, Dutch and Portuguese parts of Africa with the former Belgian Congo lest there be any doubt on this point), the Russian Empire was angelic, and compared to the dark empires of Islamic and Pagan tyrants, well, if Britain existed as a check on Russia, then Russia existed as a check on these. The Ottoman Empire was diabolical and should never have been assisted in the Crimean War - the prolongation of its existence directly facilitated the genocides against the Bulgarians in 1875, and the Armenians, Assyrians and Pontic Greeks in 1915, and other genocidal actions - any time the Ottomans sent in the infamous mercenaries known as the Bashi Bazouks, the results were usually genocidal.
The USSR was, as Ronald Reagan said, an evil empire, but in contrast Czarist Russia, for its faults (especially after the uncanonical and illegal interference in the operation of the Orthodox Church by Czar Peter I), consistently protected Christians from genocide at the hands of Muslims.
The earlier Grand Duchy of Kievan Rus, where Russian and Ukrainian civilization, was a blessed place, the only medieval European country with no capital punishment, and where Orthodox Christianity was not just the official religion but the way of life. Unfortunately it fell victim to the Mongolian invasions, and the Muscovite regime that followed was less idyllic, particularly under the reign of czars like Ivan the Terrible, who was rebuked by St. Basil the Blessed, for whom the cathedral built at the direction of Ivan was later named.
Now this is not to claim the Russian Empire was devoid of faults. It mistreated the Jews and engaged, like the Ottomans, in occasional pogroms. Its secret police devised anti-Semitic conspiracy theories which still result in Jewish deaths at present. It illegally and uncanonically seized control of the Russian Orthodox Church and forced through westernizations under Czar Peter I, and subsequently was responsible for the spiritual stagnation of the country in the 18th century, and it also for a time violently oppressed those opposed to the liturgical reforms of Patriarch Nikon (who would be the last Patriarch until the Holy Synod was restored St. Tikhon was appointed in 1917; he was later arrested by the Soviets and brutally mistreated, dying in prison as a confessor for Christ). Worse of all, the failings of the Russian Empire allowed for the rise of the evil Soviet Union which in turn agitated Europeans causing the rise of Hitler and National Socialism. Had the Imperial government done more to improve the conditions of the urban population and had it refrained from engaging in WWI, that could have been avoided, but then again without the Soviet union it is likely an Islamic movement would have arisen sooner and become more widely adopted, since the existence of the Soviet union engendered a series of pro-Soviet and pro-Western secularist regimes in the Islamic world which were not interested in the enforcement of Shariyah.
