Inherently, no. This is due to a cultural and societal decay that has occurred over the last several decades. Only a smaller portion of such violence is due to mental illness. These tend to be the high profile variety - such as school shootings. Most of it , though is just just the acceptance and celebration of violence by certain groups. Much of that can be linked to poor parenting , dumbing down of educational standard , learned hatred of Country etc etc. It’s more cultural than inherent from birth. More nurture than nature.
