I believe the morals of an individual come from the environment he/she is in and the experiences that they go through.
For example, a young child may see that their friends are littering on the sidewalk and that person would begin to think that it may not be as bad as he is taught. Later, that child may be scolded or punished by his parents and learn that the act of littering is not to be done and is wrong. This is an example of learning morals from experiences.
Alternatively, a boy growing up in Nazi Germany may be taught innumerably in school and at home about how the Jews were the root of Germany’s problems. He will eventually think of it as a moral obligation to help eradicate this population from his country or even the world. This is an example of learning morals from the environment.
However, many things are learned as a result of common human suffering such as seeing another man die may make one think of murder as a crime worthy of severe punishment.
No one is born with morals. Some morals are understood rather quickly, yet others take time and experience to develop.
Thus, we can infer that every single person has some flawed ideals of morality just as humans have many other types of flaws.
