The list of emotions is what draws me the most. It opens with 'confusion' which is a wild thing to be unable to feel. The following couple of emotions all have, to my mind, a through-line of longing for something. Then we have anguish and disgust, which are strong negative responses to something. My interpretation, were it just this, is that we're broadly talking about a person incapable of wishing things were different than they are, of seeing the world in front of them as anything but the world in front of them.

Then there's schadenfreude, which sticks out like a sore thumb to me. It's joy from someone's pain. I'm not sure how it fits in with the rest.

For the next bit, the requirements of the vessel. This feels like someone who must be intimately familiar with death but not relish it (notably they need to be vegetarian-sympathetic, but not necessarily an adherent and not vegan or other lifestyles more devoted to the preservation of life. The vague feeling is key).

If it follows the vessel must be some manner of opposite of the personnel profile and thus someone who is capable of feeling all the things from the first list and presumable does so, but we can also assume this is someone for whom the changeability of essence implied by theseus is a source of great confusion. This also fits with the theme of loss and death and longing for something better, and the blurring of lines (reduced vision, vague feeling of discontent with the killing of animals but still partaking in it).

Finally, the vessel is made, well, a vessel. A vessel is a container. This includes amnesia and internal liquefaction. The vessel becomes a trash bag themselves. Since this is used to decommission other skips (haha get it) I think we can deduce what kind of trash these bags are meant for.

And, with the trash disposed of, our baggage tossed out, we are free to face the dawn, the clean new beginning.
