Is Nihilism leading to unnecessary Violence In The USA

A car bomber has been identified as a nihilist.
Nihilism is a philosophy that asserts that life is inherently meaningless and without purpose, or that there is no objective truth or value.
This doesnt mean that nothing has any value it means everything has an intrinsic value of 1. This can be defined because if you remove humanity from the equation life and time continue on. To truly belive nothing has any value is foolish. There may be no Gods or there maybe infinity it is unknown and not our problem.
