Finances and love lost, or even cheating...I can’t make the connection on why you kill your children. Spouses kill spouses way too often, but usually spare the kids. What happened here??? Seriously.
I think what I keep reading is these people have rigid attitudes about gender. Tend to be more traditional. Lots of shame. Don't feel they measure up. They can't handle looking bad or less than or not being able to support the family.
They don't cope well with a spouse they feel they're losing control of.
I read an article recently about rape and sexual assault and how much of that stems from deep, misogynistic shame in the perpetrators. They have skewed attitudes about masculinity and manhood and thus feel deep shame when they don't feel they measure up. So they take it out on women via rape.
It's similar here. These are typically inneffectual, maybe secretly insecure men who can't cope with rejection or what they feel is failure.
They're defective. What can I say.
Of course it's all conjecture right now. Did he kill them to be free of debt and to be with someone else? Did he kill them to "spare" them the indignity of having to live in debt?
Did he intend to kill himself but chickened out like the coward he is?
Did he decide to kill them all because he became insensible with desperate, narcissistic rage at the thought of losing control and having them leave?
I think the last one is going to be more likely for men with annihilating, possibly personality disordered mothers.
I think these types really veer between either psychopathic creeps who want a "free" and "better" life, like scott Peterson and Chris Coleman, and narcissistic losers who are incapable of coping with failure or loss.
