Because genocide is wrong.
There have been, unfortunately, a fair number of genocides. The word was coined to describe what the Turks did to the Armenians. Later, the Nazis committed genocide against Jews. The Serbians committed genocide against Bosnians, the Hutis in Rwanda committed genocide against the Tutsis. Recently, the Islamic State (ISIS) committed genocide against the Yazidis, and the Rohyngya are victims of genocide in Burma.
Justice Commandos Against Armenian Genocide happened in 1970.

Because genocide is a horrendous crime against humanity and everything possible should be done to prevent it from ever taking place again.
Genocides typically last until (1) a foreign army intervenes and shuts down the genocide (such as in the Jewish Holocaust, Rwandan Genocide, or Cambodian Genocide), or (2) the genocide is generally deemed to be complete or successful (such as in the Armenian genocide, genocide against the Wampanoag). There is no set time frame in either case.
