Why do people hate anything? Why do xJws hate the WTBorg Inc?
It obviously has to do with personal grievances or upbringing.
The Lamb of God taught that we should show love to all of our fellow humans, even those we consider to be our enemies. It has always been wrong to contemplate or to carry out murder of anyone.
Somehow society has taken a wrong turn in that it spawns murderers and killers. Or, society truly is under the influence of the Wicked One, the Father of the Lie.
