Abstract
Teaching genocide against the Tutsi helps students to understand what is a genocide, to identify its various stages so that they can be able to avoid complicity in genocide and above all to prevent it. The testimony provided by Ndutiye Gabriel in Nyanza District on 30 May 2023 can contribute to teaching through the facts it reports, since we conceal in his story the cruelty of the massacres, some genocide ideology indicators which accompany the killings sometimes without understanding the meaning, but also his attitude after the genocide.
