Do any negatives choose not to graduate?

[Jade]

From my understanding, negative entities move on to fourth density because there's more power to be had there. Why stay in a puny human body when there are untold infinite powers to be experienced beyond this planet?

17.25 Questioner: How did Taras Bulba, Genghis Khan, and Rasputin get harvested prior to the harvest?

Ra: I am Ra. It is the right/privilege/duty of those opening consciously the gate to intelligent infinity to choose the manner of their leaving of the density. Those of negative orientation who so achieve this right/duty most often choose to move forward in their learn/teaching of service to self.

It's one of the big differences between the positive and negative path - positive entities, upon achieving harvestability, want to stay and help those who would be left behind. Those who are negative entities I'm guessing want to move forward so they can be more thoroughly exploitative of those left behind in confusion.
