TOKYO: Shinzo Abe, the longest-serving prime minister of Japan, has died. It was a murder caused by a personal grudge rather than political terrorism. And it was not a direct grudge against Mr. Abe. A religious group had supported Mr. Abe, and a murderer with a grudge against the religious group killed him. Murders targeting politicians are often related to political messages or claims. This is a very unique case in that the murder was committed out of a personal grudge, not against the individual for what he did, but against the organization that supported the individual.
