I have a solution but you won’t like it. For most if not all of our lifetimes, people, smarter and more interested than us have been asking a question...but it was the wrong question. They asked WHY.
Children ask “why” and make it a game. Child,”Why?” Adult:,”Because.” Child,”Why?” ad infinitum. It is a loop.
When we in the forum ask WHY, we are seeking unknowable answers. The internal processes of the DP9, beyond what their diaries tell, and their speech were not recorded, thus unknowable, now or ever. We will never know the “why” of their motivations.
The better question to ask is HOW. Asking this questions leads to definitive answers. I will not bore you with the “how” of the DP Incident as we understand it. It is simply the chronicle of what transpired. Example How did Igor die? He froze while walking in deep snow and succumbed to hypothermia. How do you know? It was observed and reported that way. (Conspiracy buffs just hate this because they argue we must trust the sources. They patently do not!)
I will go to conspiracy theories. Instead of asking “Why” try:
How were conspirators involved?
How were they hired?
How were they equipped?
How were they transported?
How were they paid?
How can you prove the truth of each of your assertions (hint, follow the money)
Asking and answering “HOW” produces factual answers. Asking WHY leads to supposition and an endless loop of WHY-BECAUSE chatter. As we have seen on this forum, there are no definitive answers when asking ourselves or each other WHY.
When people like Teddy go to the woods, she is seeking HOW things happened, not WHY they happened. We can not know the minds of the deceased, only to superimpose our own identities on their bodies and play forensic mind games. But, that's what it is.
If we want to know about the flashlight on the tent, fire at the tree etc., ask HOW and then HOW DO I KNOW. It is far better than asking WHY.
In closing, I expect push back. It changes nothing. Asking better questions will.
