Authentic moral conscience, however, is not merely something that I roll up my sleeves and produce—the product of having weighed my feelings, likes, dislikes, my friend’s opinion on the matter, advice from others, and so on. While all of this might serve to help me arrive at a genuine judgment of conscience, that judgment—if sound and genuinely proceeding from conscience—will proceed from the core of my being, and will correspond to objective moral norms anchored in the truth about what perfects us as human persons. It will be a weighty and carefully distilled judgment of what—given the objective ends of human nature—is reasonably required of me (or someone else) in the present circumstance.
What does it mean to have one’s conscience seared? To answer that question, I consulted the godly writers of yesteryear. Adam Clarke described it thus: “One cauterized by repeated applications of sin, and resistings of the Holy Ghost...”(3) The Fausett Bible Dictionary explained it as, “…a hardened determination to resist every spiritual impression…”(4) The Pulpit Commentary said it is “the gradual deterioration of sensibility produced by (habitual sin).”(5) John Wesley likened it to, “drunkenness of soul, a fatal numbness of spirit…”(6)
Sigmund Freud regarded conscience as originating psychologically from the growth of civilisation , which periodically frustrated the external expression of aggression : this destructive impulse being forced to seek an alternative, healthy outlet, directed its energy as a superego against the person's own "ego" or selfishness (often taking its cue in this regard from parents during childhood).  According to Freud, the consequence of not obeying our conscience is guilt , which can be a factor in the development of neurosis ; Freud claimed that both the cultural and individual super-ego set up strict ideal demands with regard to the moral aspects of certain decisions, disobedience to which provokes a 'fear of conscience'.
