For Ponerology: book by Andrew M. Lobaczewski,
Political Ponerology,
article by Laura.
For psychopathy: i am sure a search in the forum will bring many results (psychopathy, psychopaths). Books : Martha Stout, the sociopath next door; Cleckley, Mask of sanity (a link to the online version might be around the forum if i remember correctly); by Robert Hare, Snakes in Suits AND Without conscience.
Of course there is also the
Cassiopaea Glossary for any term discussed that you don't understand.
