Suppression, 2

Investigating each of these labels is definitely a basic of what we’re facing here, and I definitely invite you to do it thoroughly. There are different approaches to the subject, coming to slightly different definitions, defining slightly different lists of characteristics, and so on; the point is knowing and looking at all this from an unbiased and result−oriented point of view; after all, all measurement tools have plays and tolerances and require to be used wisely, which includes using them synergically. And then… by their fruits you will know them, isn’t it?

This said, my first remark is that each one of those labels draws our attention to a facet, so we’d better evaluate the usefulness of each one:
Psychopathic inferiority, moral insanity and moral imbecility highlight that an individual is not up to the minimum requirements for the survival of society – please note well: the survival of society, regardless of his or her own, insightful and forward−looking an observation.
Manie sans délire highlights a key observable – or rather hardly observable – facet: such individuals are almost always invisible, as very few of them show conspicuous or even visible signs of what they really are.
Guiltlessness highlights a key inner facet: they act as if they had no conscience at all, which means they are liable to do literally anything the conscience abhors – which in turn means that anyone who does have a conscience, and who is incapable of conceiving that someone else does not, is at risk of being stabbed in the back.
Psychopathy is actually too vague a term, meaning everything and nothing, to be of any use: the suffix “pathy” meaning “what” – a disorder, and the prefix “psycho” meaning “where” – in the psyche, the word in itself conveys no further information and thus is of no further help; moreover, it even worsens the scene due to the sabotage suffered by the word psyche, which was created to mean the soul – whatever non−material part of the human being, and then usurped to mean the brain – whatever material part of the human being, thus generating further malicious confusion.
