President Trump has called the killing in Las Vegas "pure evil" and yet the actions he calls "pure evil" are nothing but the fruition of a gun culture which he has promoted when he accepted the endorsement of the National Rifle Association and bragged about it.
St. Paul writes in his letter to the Galatians 6:7, "Do not be deceived. God cannot be mocked. A man reaps what he sows." And Americans are reaping what they have sown, aided, and abetted. Nevada has the most lax gun laws in the nation, and gun shows occur every week in Las Vegas where guns can be purchased without back ground checks. Guns, the purveyors of injury and death, are glorified and promoted.
To see this kind of gun violence is to be expected in a culture of perverted values and incentives. To demonize an individual behaving in a culture which not only condones but encourages a glorification of guns is not pure evil but a huge societal mistake.
The gun culture in the US is in violation of many of UUs principles. It glorifies violence and attack rather than compassion and peace. UUs stand on the side of love not destruction.
