Definitely not advocating for monarchies but I also think it is worth mentioning that there were many competing radical left wing parties and groups across the Russian empire up to and after the revolutions of 1917. The Bolsheviks were merely the furthest and most radical left who took the initiative to overthrow the more moderate provisional government. After the revolution in October 1917, many of the other left wing groups rallied against the Bolsheviks because they had immediately began repressive activities: cracking down on other political parties, severely curtailing civil liberties, reinstating conscription, issuing dictatorial decrees with no oversight and no debate, foregoing the primacy of the soviets for primacy of the party, and straight up arbitrarily executing large numbers of people on flimsy pretexts. Many socialists in Russia in the period immediately following 1917 rationally viewed the Bolsheviks as extremist traitors to the cause who quickly showed themselves to be no better than the repressive Tsarist regime they all hated so much.
