I think you are unwell
You certainly have anger issues
You think that because its reported that this young woman had serious mental health problems and was recently an inpatient in a psychiatric hospital and it is highly likely that a young woman who tries to kill four people is probably mentally unstable means that I am enabling awful events like this to happen ?
You need to go and see your doctor
Which part of my first post where I say this is a terrible but thankfully rare incident didnt you read ?
