“The liars punishment is not in the least that he is not believed, but that he cannot believe anyone else.” George Bernard Shaw
A white lie here and there is innocent. We all tell little white lies so as not to hurt the feelings of others: “your haircut is nice”
Those who lie more often than that, who do it consistently, create their own torment. The biggest side effect of lying is the liar can’t trust anyone else. The liar can never believe anyone else. A liar who does it well always suspects others of doing the same thing to him.
The better a person is at lying, the less he or she will believe anything anyone else says. They create their own hell, never believing anyone. They cannot love, for love requires trust. They might be loved, but only until their lies are found out.
Eventually, the liar becomes a lonely person. A lonely paranoid person.
