A favor you do to the killer and a favor the killer does to you.

Getting Photographed (by killer) while getting killed AND getting killed while photographing (the killer unintentionally)

A favor you do to the killer : A Filipino politician took this photo of his family moments before being assassinated.

These two pictures show a shocking but opposite attribute of a person getting killed.

1. The person does enough in a split-second before dying, a favor to the killer.
2. The killer does enough moments before killing the victim, a favor to the victim.

** FAVOR: taking the picture of someone is a favor. In 1. it must have helped the cause of the victim. In 2. it must have also caused favor to the victim, because it confirms who was killed, by whom. Read the article in the follow through link, or read captions. Its mandatory.
