The reason things like this happens varies. Sometimes people do have some mental issues, which may or may not be already diagnosed. Sometimes those who do these are already on some really messed up psychoactive medication that, when they don’t take it, they become EXTREMELY dangerous.
Other times it can be because many in our generations and younger have become, for lack of a better word, pussies, in which words said to them are worse than actually beating them up. It’s harsh to say but in my opinion it’s true. People are soft now, and that coped with some underlying mental health issues can create a person who becomes very violent because you just said something wrong.
As a side not, in cases like this, you don’t hear the MSM blame the knife, do you? Had it been a gun, it’d be a different issue.
