It’s crazy how the assassination and the public acceptance of the assassin’s goals sound like something out of Persona 5.
When you are an artist in Japan, there are certain things you will pull a massive amount of criticism down upon yourself for directly critiquing or commenting on via your art. You can't make a video game about "Hey maybe it's weird and a little not okay that it's an open secret that formal power in Japan is very closely tied to the informal power structure of what is basically a specific religious cult." Making that game will pull all kinds of formal and informal pressure down on a person's head.
... But making a game where young people look at the existing power structure and band together to defeat it, fighting all the way up to divinity itself? Not only is there a reason Persona 5 is what it is, there's a reason we keep seeing that theme in JRPGs.
Another more contemporary example would be the assassination of Yitzhak Rabin (prime minister of Israel) in 95, which had a lot of local public support.
*In some countries.
In others, the primary purpose is rehabilitation so people can eventually re-join society as "better people".
Kept the war going until the present day, too.
I actually think the assasin of Rabin was the most successful, in terms or changing history in his desired direction
