Cannot do this without Shakespeare. Everything descends from him. Bernard Spivack was a Shakespeare prof that I took every course of that I could (4 iirc). Spivack in '58 wrote:
The main point of the book is that Shakepeare created Pure (meaning un motivated) evil in at least three of his characters, Othello's Iago, the titular Richard II, and Titus Andronicus' Aaron the Moor. A never-ending debate over Shakespeares' bad guys motives is timeless. We all Know that the weight of all the Shakepearen scholarly writing is virtually immeasurable. .
Spivacks take is that even when the villain's express motive (and they do), they neither need it or mean it. They are just evil period, satanesque, and are misleading in citing reason.

The above is Aaron's monologue from the play Titus Andronicus by
William Shakespeare and it is an illuminative expression of an evil man
Act 5 Scene 1
AARON
Ay, that I had not done a thousand more.
Even now I curse the day – and yet I think
Few come within the compass of my curse –
Wherein I did not some notorious ill,
As kill a man or else devise his death,
Ravish a maid or plot the way to do it,
Accuse some innocent and forswear myself,
Set deadly enmity between two friends,
Make poor men’s cattle break their necks,
Set fire on barns and haystacks in the night
And bid the owners quench them with their tears.
Oft have I digged up dead men from their graves
And set them upright at their dear friends’ door,
Even when their sorrows almost was forgot,
And on their skins, as on the bark of trees,
Have with my knife carved in Roman letters,
‘Let not your sorrow die though I am dead.’
Tut , I have done a thousand dreadful things
As willingly as one would kill a fly
And nothing grieves me heartily indeed
But that I cannot do ten thousand more.
So, for evil? The Bard is my Boy and Aaron is at or near the top of my list
