You ask, in short, whether it would not give us a lot of satisfaction when we look back and are sure that we have followed our conscience.. I am perplexed on that issue. My take on it..
That is a very complex issue.
Path of morality is difficult to tread, especially if things would have been easier if you took a none too proper route and you got away with it too.
Often, people manage to clean the dirt they have accumulated in the path they travelled, once they have reached the destination somehow.
Something like killing the cow and compensating or atoning for the sin by making gifts of footwear made of leather.
Satisfaction we get from righteous actions are, on most occasions, idealistic and are of very little practical use.
Often, we would declare that we have gained punyam and all but no one is sure about what punyam is or what punyam will do to him.. in the present or future.
But a person comes by some money or some object of pleasure, be it through righteous means or through deceptive methods, that money or object would give him the same satisfaction and the means adopted to gain the resources hardly matters. That is a physical experience. It is evidenced by immediate enjoyment.
Such evidence can never be produced with certainty about the results of the righteous actions you ever undertook..
What is conscience after all? An abstract concept.. not yielding much to logic or definitions.
Of course, we do not live by food and pleasure alone, and we look forward to attaining something more sublime.. although the degree or intensity of such yearning can vary from individual to individual.
If you feel satisfied about following your conscience, do so.
But never expect anything extraordinary.. or miraculous.
You can evel meet with failure, utter collapse, after following the path of righteousness all your life.
Take Gandhiji, for example.. Ultimately he fell victim to a bullet.. a nasty death by our religious standards. He was not a Kshatriya, fighting an armed battle.
Krishna fell to an arrow shot at him from some obscure source, from some obscure hunter.
Arjuna, Bhima, the twins, Draupadi, .. all fell during the mahaprasthanam without reaching the true destination.
So, if our idea is to seek the pleasure, celebrate the success of reaching the right summit, then there is an even chance that we might fail and fall short of the summit
But if we try to enjoy the journey, and enjoy the journey in the righteous path, we can be happy about such a journey. That is all.
