if you asked me this question several years back, I would have said 'yes' without even thinking. While I will say that she definitely contributed to the fall of the regime, she did thinking that she was doing right. Yes, a road to Hell is paved with good intentions, but let's think about this for a second. She was a woman who was desperate to provide a heir in order to secure the succession, yet, once she does, he ends up sick with an incurable illness that came from her side of the family. I'm sure guilt had a great deal to do with her decisions when dealing with Aleksey, and out of that guilt, coupled with desperation, she trusted a person like Rasputin. We know what went on, so I don't need to rehash the entire fiasco of World War I and the Empress's attempt to run the government and basically having Rasputin dictate and her blindly following. However, I will say that it was all done with a hope that somehow her son and Nikolai's heir will survive and be able to take the throne. I don't want to judge too harshly, because in all reality, I'm not sure how I would have acted if I were in her position. A mother will do anything to stop her child's suffering, and unfortunately, in this case, it led to a bigger catastrophe.
