Is It Wrong to Withhold Information?
If is it information that someone has a right to know – something that affects them – then you do not have a moral or ethical right to withhold it from them, even if they never specifically ask you for it. On the other hand, you are under no obligation to volunteer information that is private to you or some third party and/or that is inconsequential to the would-be receiver. In fact, revealing such information, some of which can be classified as gossip, often does more harm than good.
But even some information that directly affects a person shouldn´t necessarily be revealed to him or her. We´ve all heard that "the truth hurts." Very often, it does. And there are situations when we must confront someone with it just the same. However, we not required to present someone with a painful fact if doesn´t have any kind of redeeming purpose. Inflicting hurt on someone just because it´s the truth (frequently out of spite) is both unethical and immoral.
