Quote:
Genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:
(a) Killing members of the group;
(b) Causing serious bodily or mental harm to members of the group;
(c) Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
(d) Imposing measures intended to prevent births within the group;
(e) Forcibly transferring children of the group to another group.
-Genocide Convention, Article 2
Article 2 sections c and d should be relatively straightforward to understand. By sundering the Ancients, and with it the world, the physical destruction of the group is assured, and this was done in a calculated fashion, as it has been previously indicated in Q&A sessions Venat purposely allowed for Emet-Selch, Lahabrea, and Elidibus the ability to avoid the sundering attack. Section d is also relatively straightforward as well since the measure she took, which was sundering the world, would ensure no more births could occur from the population and, in the case of Emet, his children also would be sundered despite the obvious ancient lineage.
Article 2 section b is a bit more complicated but is shown inside of the Nier ReIncarnation crossover event where previous life was unable to understand language and had to relearn how to speak. In addition, upon sundering the world, Venat introduced to the new life suffering which the Ancients had not suffered prior, which would include decreased resistances to the elements as well as other agents related to illness and pestilence, both can only occur if there is a change in the constitution to the Ancients that made them weaker as a species significantly and the reduction of their lifespans from countless millennia to, at best, 500 years in the case of Viera, but somewhere near normal human lifespans for all other races. These would constitute significant harm both mentally and physically, and I only need one of these to have the basis for the argument.
Finally, there is the intent issue. Genocidal intent can be determined either directly, which would be someone admitting to it or evidence to directly prove the elements described, or through circumstantial evidence, which has been used to determine intent involving genocide IRL multiple times. Venat outright says she is going to sunder the ancients and has the forethought to also be careful to not sunder very specific ancients as to avoid causing issues related to a perceived timeline that she was told, as such I would not need to go much further beyond that. Were circumstantial evidence be needed, she unleashed untold amounts of suffering onto the lifeforms created after the sundering occurred, and would these individuals be treated as shards of the original ancients, would also constitute the ancients as well. This callousness would be great enough to also fulfill that requirement were it needed.
