What did nicholas ii think of rasputin?

Nicholas had an unsteady relationship with Rasputin, and was never as committed to him as his wife, Alexandra. There were times where the Tsar and Rasputin had disagreements, and on a few occasions, Rasputin was banished from the royal family. However, through Alexandra's persuasion, Nicholas managed to put up with Rasputin, especially as he was supposedly helping his son, Alexei, to survive through his suffering of Haemophilia.
