How often are you tormented by thoughts about the wrongness of your act?  How often do you think about what conscience is in general, does it exist at all or is it a fiction of people?  How often do you think about whether it is correct to do this? 

 In our world, there are many things for which there is no right answer, the same actions can be bad for some people and good for others at the same time, so is it worth torturing yourself for the "wrong" of your actions / decisions / thoughts?
