The Italians never ran extermination programs like, nor behaved with the indescribable institutionalised inhumanity of, their German and Japanese Axis partners.
Why?
The Italian Fascists focused on Jews as a problem and in the late 1930s passed laws severely oppressing and dispossessing Jews, as did the Nazis, but the Italians never moved to the Nazi model of extermination nor did they display by relentlessly inhumane treatment the racial contempt of their other Axis partner, Japan, towards people they regarded as inferior.
In part this might be explained by Germany supplying the death camps etc for Italian Jews, but this didn’t have much impact until after 1943 when the Nazis effectively controlled Italy.
Was there something different about the Italian character or experience, perhaps going back to WWI experience, which explains its difference from German conduct? But that still does not explain the difference from Japanese conduct as Japan, like Italy, was an Ally in WWI and did not experience even the tiniest fraction of the suffering which Germany experienced during and after the war.
