@revelette1,
Snood made a smart observation a couple of days ago which others have also made. He said, "The cruelty IS the point".
More broadly, as others have suggested, such breaking of moral and legal norms looks to be a purposeful display of power. This is Trump's gift to the modern American right and they've quite eagerly followed his model. Blatant lies, cheating, cruel insults, etc are not moral failings, they are both funny and admirable.
Much of this has earlier origins, for example, the Brooks Brothers riot in 2000 (Roger Stone being a key player). But Trump has jacked it way up. Now, if things go further south, the right will have no trouble whatsoever in recruiting cadres of brown shirts ready and willing to assault or even murder those deemed the enemy. This isn't merely partisanship. It is "partisanship" as conceived by psychopaths.
