As a war reporter he travelled to and wrote about several contemporary war zones, and especially the former Yugoslavia. What he saw there, or rather what he heard people talk about—both victims and perpetrators—convinced him that when people do harm they do so because they enjoy it—not because they are sick as clinical psychology thinks, or because they have suffered discrimination and exclusion, as sociologists like to believe. Individuals (and groups) are violent because that fills them with satisfaction; and that is what makes violence incurable, in the sense that it cannot be overcome (within individuals) or coped with (by societies).
