Some anti-cloning campaigners feel that if a clone was born, knowing that it was a clone, then it would have no sense of "self". It would always believe that it was born for a reason, whether as a scientific experiment or just to save someone else.

For this case I believe it is still a case of environment. If the family of the clone treated it as a normal kid, it would believe so. Of course someone else could come along and inform them otherwise, but with a good family, it would not affect the clone. On the other hand, the bad family who doesn’t care about the clone would cause it to feel like nothing but a mindless automaton.

A clone, knowing it is a clone, would also believe that it should not have a life. Life, in the figurative sense, is a course of time in which we make choices that affect our lives, good or otherwise. A clone would believe that its life has already been lived out, all its decisions already made. All it has to do is wait to die. Like a person’s personality, that can be changed. Since knowledge is not passed on through genes, as long as no one tells the clone what the original’s choice was, the clone could still live out its own life, falling and winning on its own.

So far, Mother Nature has proven this "problem" invalid, through her own genetic play, called "Twins". People would assume that twins, being from the same egg cell, would be exactly the same, down to how they brush their teeth. Research has shown that twins, under different influences, have developed different habit; for example, one twin could comb his hair right, the other one left. Personalities have also varied through environment.
