The malice I see in Trump is mostly from his grudges. If someone slights him in any way no matter how small, it consumes him. He has to "win" against that person, no matter the personal or collateral cost. As it pertains to covid, I think his actions are a combination of incompetence, ignorance (in science, and in getting govt to work), laziness and narcissism, but not really malice. I don't think he has malice for people who haven't wronged him because they aren't on his radar. If those people don't affect him personally they are nothing to him. I do think he takes a perverse joy in knowing that people are suffering, because that highlights in his own mind that he is a winner, because he is doing fine. Remember to him, everything is a transaction, there's a winner and a loser, which is why he's incapable of diplomacy and failed to get any big deals done and instead tears them up.
The reality he wants to believe in is that covid never took hold here, and it went away quickly. Back in February and March, to do anything we would consider intuitive to prevent covid would be a waste of money and effort since that is his reality, and it would send the wrong message. I think he says whatever he wants to be true and believes his own lie in the moment he says it, and good luck anyone convincing him otherwise, and not just because he only surrounds himself with yes men.
When it comes to the suffering of people who haven't directly wronged him during this crisis, he has no empathy, no capacity to understand, and doesn't care at all. So in that regard, people losing their life or their job, he couldn't care less about them. He only cares in so much as it affects himself, his poll ratings, his perception of being a winner and not a loser, etc.
He is without a doubt one of the worst human beings I have ever seen in my life. No redeeming qualities, all bad qualities. I'm sure he identifies with Commodus from Gladiator:
"You wrote to me once, listing the four chief virtues: Wisdom, justice, fortitude and temperance. As I read the list, I knew I had none of them. But I have other virtues, father. Ambition. That can be a virtue when it drives us to excel. Resourcefulness, courage, perhaps not on the battlefield, but... there are many forms of courage. Devotion, to my family and to you. But none of my virtues were on your list. Even then it was as if you didn't want me for your son."
