This is interesting, because there is still a distinction to be made between genocide and its intentional element, as Mr. Eboe‑Osuji has just mentioned, and the crime against humanity that is extermination. That exists, too. It has been proven in the case of Rwanda, and it could be proven in other situations as well. In the case of extermination, it is not necessary to establish this intention to destroy, in whole or in part, an ethnic, racial or other group.
This distinction between the two is fine for lawyers and professors. For the general public, however, it is sometimes difficult to understand. Nevertheless, the distinction exists.
Genocide is an important crime, of course; it's horrible. That said, other crimes are equally horrific in terms of their consequences for victims, such as murder, extermination, rape or deportation.
