Vicious? No, over 200,000 people are dead. I know some who've died. Trump is vicious, and cruel.
Hateful? No, I don't hate Trump so much as I hate how he's actively doing what he can to destroy the America I know.
Lunatic? Sorry, a stupid thing to accuse me of. I'm not a lunatic, simply because you disagree with me. More than half the country think he's a clear and present danger to democracy. By most measures of what constitutes a psychopath, Trump qualifies. Perhaps previously we might have considered him only sociopathic, if he's willing to even cause the death of people around him he's amply demonstrated he simply doesn't care about anyone but himself.
If you look at the 20 common traits of a psychopath (https://metro.co.uk/2017/08/29/what-makes-a-psychopath-the-signs-to-look-out-for-6885871/) Trump exhibits almost all of them.
And sorry, it's only slanderous if the statement is false. In this case it's clearly true. We can see it right there in the image: Trump taking off the mask. No matter where the virus comes from (which at this point is pretty irrelevant unless you're looking for excuses), Trump knows damned well that he's infected and infectious, knows damned well that he's already infected his own family, friends, a whole bunch of his supporters from the Rose Garden event last week, White House staff, as well as many of the US Joint Chiefs of Staff, which has put the nation at a high security risk.
No, only a psychopath would, knowing all that, deliberately continue to infect other people, and deliberately advocate that other people risk infecting other people by not wearing masks or attempting to avoid the virus. He's actively promoting the spread of the virus both by his actions and by his words, even amongst his own supporters. Even to you.
