Sagittarius is a truthful and extroverted sign. They place much too much value on their friendships and the people around them to ever lie. But if they have no choice but to lie, they will tell the largest deception known to man, typically at a reasonable cost. Capricorns abhor lying and are the sign most prone to it. But even they can be convinced to lie under certain circumstances. A Capricorn who believes they are going to be shot deserves some leeway for being lied to. Sagittarians are honorable people and would never dream of telling a lie. If you find yourself in a situation where you have no other option than to lie, try not to hurt anyone else along with you. This sign loves others too much for that. Librans are honest by nature. They may appear to be lying because they don't want to upset someone, but inside they are happy and doing nothing wrong. However, Librans can be persuaded to lie under special circumstances. For example, if someone important to them is in danger and there is no other way out, a Libran may say anything to save someone they love. Vulcans are the most honest of all the zodiac signs. They would never lie to protect someone else's feelings or hide something bad from them. They also have a very high standard when it comes to personal honor and would never compromise it for anything or anyone.
