The majority of Kornilov’s grievance with the provisional government rested around their inability or unwillingness to take decisive action against the Bolshevik, which makes it especially ironic that his attempted coup was one of thing things that led to them taking power. The attempted coup was instrumental in providing support and sympathy for the Bolsheviks, and in convicting the people that the rightists did not have their best interests at heart.
While Kornilov tried to take advantage of the widespread fear and confusion sweeping the nation to strike against the Petrograd Soviet, he miscalculated, thinking that the people would support him as an end to the chaos, when in reality, they sided with the Soviet, who was better able to mobilize them. He thought that he could convince the people that the Soviet and the Provisional Government were working together to destroy what made Russia great, he didn’t count on the people not thinking Russia was so great, and instead feeling that it should be changed for the better. Ironically, Kornilov’s attempted coup provided a fantastic opportunity for those who wanted change to prove why the Provisional Government would never work: because they too agreed that the Soviet was wrong and should be stopped.
