Answer Mussolini had many faults but he had one good attribute; he did not buy into the German philosophy of the great Aryan race and the final solution to execute the Jews. It wasn't until after he began to lose power in Italy and after he became a puppet of the German forces that Jews in Italy were sent off to concentration camps.
The question as written is very offensive because it makes the allegaton that somehow murdering millions of people can be justified. Just to be clear, murder is not an acceptable solution to any problem.
Murder is a Crime: This should not merit discussion, but alas, in the case of the Jew, it does. Murdering any person is a heinous crime. Advocating for genocide (which is what killing all Jews would be) is a war-crime and one of the worst offenses of the law and sense of moral decency that exists. There is no reason for advocating the murder of an group of people regardless of whether you may have political, social, or other quarrels with them. The best solution and the only really viable solution is negotiation and peaceful dialogue.
Those who try to justify the murder of Jews say that Jews control some global conspiracy or are attempting to rule the world. This is a pernicious Anti-Semitic lie. Jews have wanted some political influence over the century, primarily to secure better treatment in the countries where they live. Jews were historically the recipients of overwhelming discrimination. During the Holocaust, half of the six million Jews who were systematically murdered were Polish Jews who had minimal representation in the Polish national government and were, for the most part, too religious and removed from secular society to care about that. In other countries, where Jews were integrated better in the political and military apparatus, they only wanted equal rights and equal representation. Jews had fought in the German Wehrmacht (National Army) in World War I, served with distinction under the Greek flag in the Balkan Wars and against the Italians in 1940, had respected members in the British House of Commons, and played a part commensurate with their rights and duties as citizens.
Some Christian and Muslim groups allege that Jews are evil. The Christians who say this do because the Jews rejected Christ as their Savior which assumes necessarily that Jesus was the Jews' Savior without understanding Jewish objections. The Muslims who say this base their hatred of Jews on verses of the Qur'an that claim that some Jews had been turned into monkeys and pigs because God despised them and the Hadiths concerning the Jewish Tribes of Arabia. However, a religion's good or evil character should not be determined by historical perceptions of a religion by other religions but on the merits of that philosophy and ritual as expressed by those people themselves. If the virtues of Judaism are discussed, such as respect for the widow and the orphan, the view that the best man is one who cares for his wife, the desire to rebuild the world into a more respectful and decent place, and the desire to treat every person with dignity and care, these views generally align more with "good" than "evil".
There are two ways this question could be read.
1) Why did Hitler persecute the Jews in ways other than simply slaughtering them, i.e. forced labor, torture, ghettoization, etc.? -- Many of these other methods of persecution were used in order to facilitate the slaughter, such as ghettoization, curfews, forced relocations, and the like. The use of gas chambers and hit squads (like the Einsatzgruppen) was very expensive and required the targets to be densely populated to be fiscally viable. Forced labor was useful to power Nazi Germany's industrial engine and permit more Germans to fight to expand the Third Reich; it was used for basically the same reason that Africans were enslaved in the Americas. Torture was applied for information on the whereabouts of others, inhumane medical testing, and, of course, as a source for sadistic pleasure.
2) Why did Hitler target races, ethnic groups, etc. other than Jews? -- While Hitler despised the Jews based on his conspiracy theories that Jews were behind the downfall of modern Germany and, therefore, targetted them with a vengeance not paralleled in his doctrine or actions. However, his ideal was to create a racially pure Germany for Nordic peoples who had the best in physical features. As a result, he targetted the Romani and Slavs for ethnic reasons, he targetted the homosexuals and handicapped for mental/physical reasons, and he targetted dissenters for ideological reasons.

Hitler and the Nazis did not bury the Jews that they killed. The Jews who were killed in the concentration and extermination camps were cremated. Others, who were shot, had to dig mass graves themselves and they were then killed in such a manner that they would just fall into the mass graves.
