Whoops...my bad.
Okay, I think conscience is the voice of that part of yourself that wants, more than anything, to be good. It is subjective, in that what that voice says depends on what you think a "good" person would do.
I think if people really considered whether they would prefer to be dead or to face the realization they are a bad person to the core, a blight on humanity, a lot of people might choose death. We may be selfish, want material possessions, want to succeed even if it means others must fail, but still inside somewhere there is a part of us that wants to be good. We often compromise between this voice, and the voice that tells us to do whatever it takes to get what we want, by rationalizing and finding ways to justify that we are good depsite selfishly trying to please ourselves at the expense of others.
Do children have a conscience? I think there is a first time the child finds itself conflicted in what it wants. The moment the child wants both to steal the candy and to have its mother's admiration, it is conflicted and it begins what we adults all take for granted -- the process of having multiple "voices" in our heads that often disagree on what we should do.
Prior to that conflict, the child was of singular, united mind in saying and doing whatever it wanted. Some might say the child was at that moment pure conscience, before the bullshit of society overlayed that purity with our garbage to create a conflicted individual. But then again, it is pretty obvious that young children act purely selfish, not purely selfless. So, it might be more accurate to say that a child starts out with no conscience and that the voice of our conscience is the intruder, the squatter, not the voice of our selfish desires.
It occurs to me the moment a conscience develops might be the precise moment a child first realizes that love is not unconditional. That it's parents' feelings toward it are dependent on how "good" they perceive the child as behaving. Since the child probably realizes at a very core level that it is dependent on its parents for sustainance, for protection and for comfort, it thus develops a strong urge to BE good that begins to wrestle with the prior pure, thoughtless selfishness the child had been used to.
I think at some point, the child's thinking becomes more complex, and it realizes that it need not BE good to have its parents' love, but only to be PERCEIVED as good. This may be the age when children learn to lie, and start misbehaving and then lying about it. Generally, they are so inept at it that it does not work, they are caught lying and perceived as even worse for having lied, and they go back the urge to BE good as the only way to ensure they have their parents' love. But the voices of unashamedly selfishness, and perhaps the newest voice of being secretively selfish, are still there and continue to war with the voice of being truly good.
Well, that is all theoretical child development. It is a little hard for me to accept (even though I wrote it) because I prefer the idea that children are born truly good. Hmmm...I wonder if pure, honest and unashamed selfishness might be good, with the caveat that we should view the "I" that is being selfish not as ourselves as individuals, but as ourselves as the human species or the Earth life entity or as the universal one-ness.
That goes back to my view on enlightenment, that pure happiness and fulfillment can be found in viewing yourself not as an individual, but as a part of the universal whole. You then lose your fear of death or pain and seek the good of the universe. While that may seem altruistic. if you are PERCEIVING yourself as the entire universe, simultaneous with devoting yourself to the GOOD of the entire universe, then you are purely releasing your selfishness in a way that you need not be ashamed of.
Maybe that is part of the joy of enlightenment, of having the sense you are one with the universe, because it allows you to reject all voices that were put upon you by society and culture, and become your complete, original and selfish voice and, moreover, to reconcile that voice completely with the later voices telling you to be good, or to hide your selfishness. Essentially, you stop having any crises of conscience, any internal conflicts over your actions, and you become one united voice in your head.
