Weird news - Hong Kong - Man kills his parents and then cooks them

Sometimes you read about real weird things and wonder as to how they can really happen. This is one such case. Killing other humans happens on a regular basis, with people doing murders for a number of reasons - these could be gang related, these could be because of strong emotions such as anger, hate, frustration, jealousy, etc. However, it gets more rare when a person kills his / her family members, especially parents; although even that is not unknown. However, things get really weird when somebody kills their parents, has no clear reason and then gets rid of their bodies in such a crazy manner. Imagine killing parents, then removing their heads and cooking their bodies and placing the cooked parts along with rice in lunchboxes. For somebody who is investigating such a crime, it would be difficult to comprehend whether they were indeed going on the right track, with such an unusual and barbaric crime (link to article):

An elderly Hong Kong couple were allegedly dismembered by their son and his friend before being salted, cooked and packed into lunchboxes "like barbecued pork", a court has heard.

The severed heads of 65-year-old Chau Wing-ki and his wife Siu Yuet-yee, 62, were found in March last year, stuffed into two refrigerators in a bloodstained apartment, days after they were reported missing.

The other remains were found in a rubbish bin, cooked and packed into lunchboxes with rice, in an attempt by the duo to hide the crime after they ran out of space in the refrigerators.

How does one even sentence such a crime ? 

Weird news - Father throws his son out of the window, son dies

Fathers are typically the ones who are expected to ensure that their children are safe. In history, there are literally countless cases where parents have given up their lives to save their children, or dedicated their lives to ensure that their children have a better life. So, it seems very strange to come across cases where you find parents ill-treating their children, or in this specific case, actually causing the death of the defenseless child, one who cannot protect himself and for whom everybody expects that their parents will be the one who take care of them.
In this case, the parents had 4 children, 3 daughters and 1 son (and in these areas, having 1 son and 3 daughters would mean that the son would be very well thought over and loved by his parents), and yet the son was thrown out of a window during an argument and died (link to article):

Police added the couple was married for 11 years and the boy, Hanif, was their fourth child. They had three daughters as well. "The couple was fighting on Thursday and Hafiz, in a fight of rage, picked up the boy and threw him from the balcony of their house situated in Jodhpur's Nai Sadak area," said the officer. Neighbours informed the police and rushed the injured boy to the hospital. "The boy had sustained injuries on his head and other body parts. He was admitted in the Intensive Care Unit," said the officer, adding that Hafiz was arrested on charges of attempt to murder.

Weird news - Father kills 7 year old son over matrimonial dispute

Disputes between parents and children is nothing new, but you hear of those typically when both parents and children are adults and both have their own views (and the disputes could be over monetary issues, or over differences of opinion); but when the children are young and defenseless, one gets horrified at scenes of violence between parents and children.
Consider the following case where a father killed his own 7 year old son since he was having a fight with his wife, and this led to his taking out the anger on his own son, hitting him hard with a hammer on the head (link to article):

In a gory fallout of a matrimonial feud, a property dealer from south Delhi killed his seven-year-old son with a hammer blow to his head on Sunday. The victim, Arpit Singh, a class I student of Greenfield Public School, fell dead instantly.

Arpit's 11-year-old sister and his mother were not in the room when the incident took place. Bhupender also reportedly suffers from alcoholism. According to senior police officers, the couple had a bitter argument on Sunday after which Bhupender stomped back to his room. Sources said the argument was over an extra-marital relationship and the manner in which the accused conducted himself in public.

A father (or mother) is very important in the life of a child, they are the one who protect their children till the children themselves become adults, and in addition, it would seem impossible to find a parent who can cause their children harm.
