Here's how you know he was a whitehat (timeline method of analysis):

1. Began political career in 1993 when a worldwide operation began to counter Bush Sr. and his systematic corruption and takeover of numerous countries that began in 1989 (go see how many countries had sudden change of government between 1989 and 1991, this was the NWO being put into place) [Patriots active 1994-1999 with Contract with America, et al., possibly 1993-2001].
2. His grandfather railroaded and imprisoned by Deep State for fighting against Communists (basically); Globalist no likey anti-communists and target them with false charges; cabal targets the whole family for an offense such as this; Media continuously pushing the Class-A war criminal narrative which means they made it up
3. First stint as Prime Minister was 2006-2007 where he was continuously sabotaged by Japan DS. 2006 is about the time that things were being put into place to counter the DS (~2007 through 2012 Tea Party stuff in US).
4. Second stint as Prime Minister was 2012-2014 which Japan DS attempted to end coincident with their Ukraine coup and other worldwide events in 2014 intended to put NWO leadership in place (and start wars, see Donbass/Crimea).
5. Third stint as Prime Minister 2014-2017 salvaged by partial failure of DS to completely remove him at end of second term in 2014.
6. Fourth stint as Prime Minister and strong ally of Trump 2017-2020, ended prior to US 2020 election and looked like he was playing possum, repositioning for something that was coming (2020 stolen election);

Unclear exactly what his "terminal illness" was, but my read on this is he made statements that would make him and his family a globalist/CCP target and his security would not be this lax, especially for someone who had been Prime Minister 4x. It was time for him to have a "public death" and move into a different nonpublic, safer role.

Deep state targets and tactics are well known. If blackhats have plans to take someone out, then the whitehats staging what the blackhats were going to do anyway and then use it for a political narrative on their own timeframe to expose the blackhats is classical counterinsurgency tactics. But once the ID is burned, it is gone. No coming back with a burned ID, thus the "public death".
