From what I've read in the past about family annihilators they have many simialar traits, behaviours and may also have been actual domestic violence abusers.
And is said to often occur when a man thinks he is going to lose his family, ie that same situation that women are warned about that the most dangerous time for them can be when they tell their abuser they are leaving.
So my maybe flip thread title doesn't mean those posting have to stick to that aspect.
And yes, as the shouted out comment in court implies, there could be a mental health issue, in which case why was he allowed anywhere near his family.
Its this whole arc of male violence. At home and in the streets.
Shooters both here in the UK and the USA are sometimes recorded as having first shot their mother and then gone on a shooting spree.
And incel culture feeding ideas of violence against women.
And although more men are killed by other men, than women killed by men, this doesn't stop the basic issue of male violence.
Whether prompted by mental health, wounded pride, machismo, misogyny, or whatever, what makes men then translate this into violence.
