Because that's exactly what it is? I mean ... that's why Herme was so reluctant to take over the Fernadel's office due to what it is implying for the current office holder. Venat was CLEARLY taken back and uncomfortable when she was pressed for "her own end". She is someone clear want to continue living, yet being pressured toward her death. And yes it is death, call it whatever you want, but if look like a duck, walk like a duck, and quak like a duck then it is a duck.
Like I said Herme and Venat represented the "normal" view toward death to contradict the "warped" view of the ancient society. I mean ... Milteon was doing what she did also due to a warped view of life and death. She's not killing the world out of malicious intent, she think she's simply saving men from the suffering of living.
The problem is ... they are the killer more often then not. If someone murder you because they think you're unfit for society, would that be ok as long as they "pay respect" to you afterward? Since I do believe you're ignoring the MSG, here is the snippet from one of the quest in Elpis:
This clearly show the contrast on the view of life between Herme and the society norm.You learn that a third-generation charybdis is unable to fly due to its aetheric balance leaning strongly towards water. Though the observer in charge wishes to revert the specimen and its kind, having deemed them a lost cause, Hermes is loath to give up on them, and offers to transform in order to guide the creature skyward. The proposal is met with shock and dismay, for transforming in public is considered vainglorious and unseemly. While Hermes seems willing to bear the shame if it means saving the creatures, Emet-Selch is not wholly convinced. It is then that Hythlodaeus conceives of a solution. For this, he sends Emet-Selch off with the charybdis, while you and the others remain to assist him with the necessary preparations.
While the observer is impressed that the charybdis can in fact fly, he remains of the opinion that it would be better to simply have their concept adjusted. Hermes, however, is adamant that they continue to be given a chance to prove themselves a worthy addition to the star, and his underling acquiesces before taking his leave. With that, Hermes declares all his present tasks complete, and you set off together back to Anagnorisis.
