text: I'm not sure why so many people are jumping to the conclusion that this writer is somehow referring to the victims in this crime.
  
  I take it that he is using this passage to condemn the immoral life of the shooter.   For it is he who has committed murder and deserves death, not the victims.
  
  Sounds more like a call for the death penalty to me.
  
  It is too bad that this person posted this quotation without any attempt to provide any context at all, or explain his motive in posting it.   That was a rather irresponsible thing for him to do.  Ministers certainly don't just stand up in church and quote the Bible, without explaining their reasons for citing the quotation, and how it pertains to the subject matter being discussed.
