Sin is a sin,there is no less/greater sin than the other therefore he who lies is just a sinner like a murder or fornicator because it's the same God that gave all the commandments so if you sin against one then you have sinned against all and thus you are a sinner. It therefore should be clear that the way we view the drunkards murderer as sinners is the same angle we need to view those who lie on the phone and , greedy people, fornicator in our churches, choirs and singing groups the same way because all are just but sin.(yourself included) Remember no sin is less or greater than the other one.
