Father Allegedly Strangles Daughter Over Head Scarf

Strangling your daughter over the way she dresses? This is not normal behavior for any father. Doing it in the name of your religion is even more abnormal. As reported all over the press, Muhamed Parvez, strangled and ultimately killed his 16 year old daughter Agsa. Parvez was upset at his daughters refusal to wear the traditional muslim scarf (hijab) in public. This disgusting act of violence took place in Mississauga Ontario (a Toronto suburb). The greater Toronto area is one of the biggest multicultural melting pots in the world.
I have several questions in regard to this.
1. Can a religion have a person so brainwashed that they are able to kill their own child in the name of religion? If so I view this as a cultist behavior, not religion.
2. At what age should a child be able to decide what religion they want in life and how deeply involved in the faith do they want to be? At the age of 16 most children are actively finding themselves in life. If it means choosing not to practice the faith they were raised in or for that matter not practicing any faith, the choice should be theirs!
3. Can a parent be so absorbed in their faith that they can't see the effect it is having on their children? Obviously so in this case.
When we bring a child into this world, the health and well being of that child should be our top priority in life. Religious belief, family traditions or any other factors should be secondary? Would you raise a child this way?
