Nicholas was at Stavka where his communications with his capital depended mainly on the telegraph. He was sent reports from his ministers, his wife, his military commander in Petrograd about the (disturbances, riots, strikes, "hooligans", you chose). Thus he had information, but unfortunately like all bureaucrats they dreaded telling the autocrat bad news so the seriousness of these disturbances was downplayed. His ministers reported that the police and the army were having no difficulty in maintaining control.
On 25 Feb, at 9:00 pm, Nicholas sent his order to General Khabalov that would set in motion the train of events that led to his "betrayal." I command you tomorrow to stop the disorders in the capital which are unacceptable in the difficult time of war with Germany and Austria." It gave no guidance as to what steps he would authorize or how he wanted the general to proceed. Next day Khabalov gave the order to his troop commanders that all necessary force was to be used to disperse the crowds, including firing into them. He issued a general proclamation that banned all demonstrations and warned the order would be enforced with arms. Strikers would be conscripted and sent to the front if they did not return to work by the 28 Feb.
If you then follow a daily timeline of events from that moment on you see that there were any number of points along the way in which Nicholas could have made a difference. On the 26th the strikes and demonstrations still continued in spite of the ban. The troops went out and obeyed their orders to shoot at the demonstrators to disperse them. They returned to their barracks and discussed what they had done.
On the morning of the 27th regiment after regiment mutined and joined the demonstrators. This began the disintegration of military authority, and with it civil authority. The revolution had begun.
Khabalov appealed to Nicholas for reliable military units from the front. Nicholas decided to return to Petrograd and sent an order to General Ivanov to transfer reliable troops to the city and to restore order.
For the next five days he was bombarded with any number of proposals that might have difussed the situation and led to different outcome. Nicholas rejected all of them, intent on reaching the capital and having Ivanov put down the troubles with force of arms. Who knows what might of happened if he had made it, probably a bloody confrontation with a dubious outcome. Would the "reliable troops" have remained reliable. We will never know. His train was diverted and he ended up in Pskov at the headquarters of General Russky. There he would abdicate on March 2.
In reading all the proposals and recommendations that were proposed to Nicholas I can only see a desperate desire to maintain the imperial system and at the same time deal with the spreading mutinies and revolts. Each time Nicholas rejected them outright, or when he did bend to accept, it was too late because the proposal was outdated and events had moved on. It is agonizing to see the many times he could have made a decision that would meant a difference. Even at the last, the abdication was an attempt to save the monarchy which even that Nicholas botched.
It this be 'betrayal' then so be, let it be betrayal.
