There are lots of reasons someone might lie. You really have to look at it from the other person's perspective before making a judgement on it. Quite possibly that person could have lied to you thinking it was in your best interests. Even if it was a bad choice, I'd have to give a guy the benefit of the doubt if his heart was in the right place. If he stole from you, screwed your wife/daughter, etc., then it's cut & dried.
