Blake wrote two sets of shortish poems, collected as Songs of Innocence and Experience. Most of the famous poems come from there. You would probably dislike his long, rambling blank verse poems.

It's interesting that I'm not particularly familiar with some of the poets you list - I didn't do an American Lit option at university, though I did a lot of British poetry.

I suspect you might enjoy some of Robert Browning's character-based poems, My Last Duchess,Porphyria's Lover, The Laboratory, which is very dark, and The Pied Piper of Hamelin which you may well have read as a child, but is well worth returning to.

I'm very partial to Byron, some of whose work is very satirical and some very dark: Childe Harold's Pilgrimage, the bit about the eve of Waterloo, We'll Go No More A-Roving and Darkness

I could go on...
