The seven deadly sins (de http://en.wikipedia.org/wiki/Deadly_sins):

laziness is condemned because:

·         others have to work harder

·         it is disadvantageous for oneself, because useful work does not get done

·         an equilibrium: one does not produce much, but one does not need much either (in Dante's theology, sloth is the "failure to love God with all one's heart, all one's mind, and all one's soul" - specific examples including laziness, cowardice, lack of imagination, complacency, and irresponsibility)
