What was the worst death toll since world war 2?

The worst death toll since World War II occurred during the 1994 Rwandan Genocide, where an estimated 800,000 people were killed within a span of just 100 days. This horrific event involved widespread violence and mass murders largely targeting the Tutsi population by the Hutu majority. Other significant death tolls since then include various conflicts and humanitarian crises, but none have matched the scale of the Rwandan tragedy in such a short timeframe.
