We may not consciously realize it, but the feeling of contentment is there in our subconscious. We clearly know in what potential ways our act would have benefited others, and made a positive contribution to the environment, thus promoting ethics. Likewise, when we do something wrong, we know it. This knowledge may not necessarily come from any education, training, coaching or spiritual lectures from our elders, parents or mentors. Instead, the knowledge is within ourselves. When something is wrong, we just feel it to be wrong. Our sins generate negative impulses that we subconsciously detect. That is why, sins never offer us an ultimate feeling of contentment. The temporal pacification wears off soon as we are done with the sin, and grief dominates in our mood after a sinful deed. It is common for a hardworking student to be irritated by another who cheats in an exam. Why is this so? This is because the former knows who hard it had been for him/her to prepare for the exam and reach a certain goal, that the latter would do without putting in any effort. The hard work generates impulses in the hardworking student and he/she knows it is unethical to cheat. On the other hand, the cheater also knows that it is wrong to cheat because it requires him/her to go against the rules. However, the education we receive plays a big role in shaping our responses towards right or wrongful actions.
