What do you think of Dawkins' sentiments?

Richard Dawkins says: “In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won't find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.”

Is this true? If it's all nothing, how is he able to say there is no good and evil? The ideas and debates we have must mean we have a conscience. Without a conscience, there would be no discussion and nothing to think about. Dawkins would not have the clarity to make this statement without a conscience.
