How lying breaks trust;
Lying can break peoples trust, because it makes people feel like they can never trust that person again. They feel like they would most likely repeat what they did, because they already did it once. It breaks peoples faith in them, and often they don't believe a word they say. It makes you less empathetic towards the person, because they are liars. For instance, if someone told a lie about you just to cause trouble, your trust within them would break, and you would be angry, because they caused trouble in your life.
