Can Lying ever be Justified?

Is it ever socially acceptable to lie? Let me tell you, this has been an ongoing debate since the beginning of time. Lies can hurt, but some also argue that lies can protect. It was Kant who said lying is always morally wrong, which means two things; lying corrupts the ability to make free choice and lying also keeps others from choosing in a rational manner. A simple white lie runs the risk of potentially snowballing and becoming something much bigger and more difficult to control. In regard to utilitarian ethics, however, sometimes the necessity of a lie must be weighted by acknowledging the pros and cons of its consequences. To put this into action, take this scenario: A doctor tells their clinically depressed patient they have a 50% chance of recovering from whatever condition they have, but in reality, the doctor's tests all confirm there is a 0% chance of survival. This falls under the category of an altruistic lie under the ideology that perhaps the patient will cherish the time they have left instead of falling into a darker depressive state. There is still flaw to this ideal, as it will still damage trust of future patients once the truth is exposed. But making such big decisions that can alter the rest of our lives is very difficult to make. While not an instance where one needs to lie, such choices are similar to the trolley experiment. No matter what choice you make, someone will be hurt, and you will always leave knowing that anything that happened would be entirely your fault.
