I was discussing this with my friend and he believed that withholding the truth, be it omitting certain parts of a story or keeping an entire story to yourself, was not as bad as lying. I tried to tell him that it was in fact just as bad because you are deceiving a person. The person believes the deceit to be true, and someone's going to get hurt when they find out it was the half-way truth. It worried me that he could have such a manipulative mentality. I'm wondering: am I right or is he?
