Perhaps "dislike" should be clarified.
I can find something to dislike about a lot of people--and a lot of things to dislike about myself.
But if I choose to be with a person, whatever I find less than attractive is outvoted by what I appreciate in that person's character, attitude, and actions. And as for myself . . . well, I choose to focus on my positive qualities, and modify (to the eventual goal of abolishment) those things about me which I dislike. So to me, dislike is not an especially disagreeable term. It is a way of identifying what one chooses to emphasize and to deemphasize. And in my opinion, it has nothing to do with blaming a person or persons for something as catastrophic as a revolution.
While reading his two volumes of autobiography, I have found certain aspects of Sandro's personality which I find blustery to the point of caricature. But certainly he would have been an interesting person to know, and I do not doubt that much of what he wrote had more than a grain of truth to it.
I might find Alix overbearing. Or, I might find her generous, foolish, warm-hearted, grudge-bearing, and/or conscientious. But, I do not doubt that she was trying to do her very best--for her husband, for her children, for her country. I cannot dislike flawed people with good intentions.
On the other hand, after viewing the collection of diamonds at the Kremlin, I can say this: I dislike--hate--the attitudes of previous Romanovs that focused on accumulation of wealth over the well-being of their people, and who began the horrible cycle of abuse which ultimately led to the murder of multitudes, the Imperial Family included.
While others in my tour oohed and ahhhed, I looked at that array of gems and saw only blood.
