Hunger
Every newly created daemon has their initial hesitations when the hunger gets especially bad, that hesitation is worse in those who used to be human. Not for any religious reasons, hunger is a normal part of both life and afterlife no matter who or what you are. It's just the certain taboo that comes with the relief of that hunger coming from that of your own species.
I remember my first experience in the practice fairly fondly, I was still rather young in daemon terms. It was around my 123rd birthday, I had been with an expedition of fellow lag daemons into the celestial wilds. We had been given enough supplies for at least a four month trip, it's just the gods didn't expect that sudden raid on our caravans and subsequent storm that followed. Or if they did then they never told us about it.
Anyways we were all surrounding the fire nine months into our outing and the hunger was starting to get aggressively bad for most of us. Thought it would be the end, no final stand in a battle or in bed surrounded by loved ones. But then one of the more elder daemons brought forth a proposition that made my former human blood run cold and my mortal stomach feel queasy. He had suggested that since I was the one holding the true blessing of the great distorter, that I should be the one to make it out alive no matter the cost. So in order to keep me going, they offered up their bodies to be sacrificially consumed so that I may survive.
Cannibalism didn't come easy to me at first, I had to keep myself from vomiting up what little meat the other daemons still had left on them. Even now, I'd be lying if I stated there wasn't a part of me that still wasn't nauseous if I'm pushed to that extreme hunger again.
But like everything in my new life, I got used to it. Made it to a village without much issue, though not without being the last of said expeditionary party. Over ten good lag daemons went into the celestial wilds that year, including myself.
However I was the only one to make it back out.
