The Torah is supposed to shape our conscience to the point that we instinctively only want what is truly good and the will of Hashem. Either way your conscience is not the judge because if you go by your conscience well everyone has a different conscience. The serial killers conscience tells him to kill you your conscience will say go ahead kill him and a third persons conscience will tell them not to kill him. There are people who’s conscience tells them live and let live and accept everyone or whatever free country. Who says whose conscience is right? The Torah is meant to properly build your conscience so that with time your conscience will be reshaped into a a Torahdig conscience and you will instinctively sense what is good and what is evil and you will know what to do in all situations. Obviously this will be difficult for someone who hasn’t and doesn’t immerse themselves in Torah thought and allows the world to shape their conscience.
