During their occupation of the Manor, the other Death Eaters spent a majority of their limited free time discussing the vile things they would do to the next mudblood they caught, or recount the many ways they had gone out into the muggle world and massacred crowds, vandalised homes and businesses, just because they could. Because they believed what Draco’s father had once convinced him was true—that muggles were dirty, unintelligent creatures who were beneath him. That they were afraid of magic and needed to be shown just how powerful it was. That the magical world had a right to live out in the open, to the detriment of those muggles.
