Okay kids, WAKE UP!!!
I found this article quite interesting, this is a very small part of it...
Despite the differences among these scenarios, there is a common profile of men who have killed their wives and children. Most are white males in their 30s or 40s who react badly to stress and who view their families as extensions of themselves. They typically use a firearm or knife that they have owned for some time. Often they're depressed or intoxicated. Invariably they're described as controlling and quite dependent on their families being what they envision, and believing that they are the only ones who can fulfill the family's needs.
Ewing offers a list of motives for familicide, as does Dr. Herbert Stream in Our Wish to Kill and Christine Jackman in "When Dads Get Deadly." Jointly, they cover the following reasons why men kill their families:
Losing control over the family circumstances/panic over powerlessness
Seeing only adverse circumstances ahead in life/desperation/frustration
Feeling overwhelmed and unable to let the family live while he dies
Seeing the deaths as a necessary sacrifice
Believing the children cannot survive without him
Revenge against an estranged wife, or teaching her a lesson
Grief over losing the family in a divorce
Discipline gone too far
Possessiveness/entitlement/ownership
Psychosis
Self-enrichment
Projecting their self-hatred onto the children
Killing witnesses to abuse
A joint crime with the mothererasing the family
Compassion
Duty to the family
Suicide by proxy
Jealousy of children who are getting involved with others
Difficulty adjusting to being a parent
A long tradition of abuse in the family that just continues
The idea that children must serve the parent's needs
This came from a study "Fathers who kill & why they do it". I thought the bullet list would give us a good starting point to try to figure out the motive and why CC did what he did.
