2. Does "an introduction of its cutting edge into" mean "the intrusion of this sociosymbolic contract into"?

3. Does the pink sentence mean "the usual attempt of sanctification of victims and suppressed people will be replaced with the analysis of all people whether victim or executioner, whether male or female, ..."?

Rather, in the field of aesthetic practices the psychic turning back of the sadistic drive onto the self which splits the self into both subject and object in an unpleasurable pleasurable self-shattering creates both self and other as inherently fragmented, yet able to tolerate that fragmentation. Julia Kristeva puts it,

This process could be summarized as an interiorization of the founding separation of the sociosymbolic contract, as an introduction of its cutting edge into the very interior of every identity whether subjective, sexual, ideological or so forth. This in such a way that the habitual and increasingly explicit attempt to fabricate a scapegoat victim as
foundress of a society or counter-society may be replaced by the analysis of the potentialities of victim/executioner which characterize each identity, each subject, each sex.
