Did the loss of supply of life force energy happen to the fallen angelics one angel at a time, or en masse in one grand decision and implementation? Was there any kind of divine trial for each angel that resulted in such a sentence? Was the cutting off intended to be an inducement for reform rather than a punishment? Are angels still “falling” and being cut off at the present time, or is the angelic realm stable now?

The questions you pose nicely describe how this all unfolded. It was indeed one by one that eventually so many of the angels who fell from grace crossed a line as a consequence of their own choices to be considered "beyond the pale." And that was a decision made by Creator, in a sense, assessing the status and evaluating the consensus of the other angelics still in divine alignment, after having made many attempts to save each and every one, and only when those attempts failed was the decision made to, in effect, cast them out with respect to energetic support. Even now, we have not given up hope for a turnaround, and indeed several races of new beings were created, each in turn, to solve the problem of evil and rescue the fallen angels from the oblivion where they are headed. So you can see, rather than being harsh and quick to condemn and punish, if anything, we are overlenient in allowing continued existence and free rein, even of perpetrators, while attempts are made to persuade them to change. What this means, in a practical sense, is that many, many beings continue to be harmed on a regular basis while we are waiting for a time of deliverance, which now falls on your shoulders as human beings to arrange, if it is to happen at all. We continue to be patient. We are certainly not happy about all the suffering but always take the long view that "Until it is hopeless, we will not give up," but we look to human to justify that continued existence of all that is currently underway. If you step up and take on your healing role in earnest, and in large numbers, you will fulfill Creator's dream that the evil is not an insoluble problem and an inevitable catastrophe, but something that can be guarded against and managed if it arises. The process of offering hope once again to the fallen angels is what your channel and his compatriots are doing with the Lightworker Healing Protocol, to offer a path to healing for them. That, indeed, can save them and their brethren if enough can be reached in time to turn things around. Things are relatively stable among the angelic realm, but there needs to be an undoing of the separation and fall of so many taking a dark path to help them return to the fold. Until then, the danger continues that it will be unstoppable and spell disaster for all in the physical realm of the Milky Way Galaxy.
