A lie is always a lie no matter how sweet sugarcoated it is. A little lie can cause a whole disaster if care is not taken. When it comes to trade, it shows how unstable and unreliable someone who tells lie just to try convince someone to get in a project just for they telling lies to benefit. That is too dirty of an individual. I believe sometimes people tell lie just to cover up something's for their friends or loved ones but no matter how tough the situation could be telling a lie could end up excavating things beyond what one could imagine.
I have never seen anywhere lie after being told does good but rather harm the situation making it escalate.
This is a very honest statement, but it is not always the case and not everyone is like that he does not lie. You should also think about yourself if you are so honest that you have never lied to anyone, depending on the situation you may have lied to others many times. If no one is harmed by a lie told by someone, then that person cannot be identified as a criminal. So one can be considered guilty if a major crime is committed by lying, but not otherwise.
