Somewhere between options 1 and 3, I think Giuliani would be generally remembered well even if often attacked by liberals if he had just quietly retired from politics after leaving the mayorship, his partisan shilling afterwards and 2008 presidential campaign cost him most of his post-9/11 goodwill but I think might've been mostly forgotten had he retired from politics after that and would be after his death...but his actions with Trump including speaking before the Capitol riot...yeah that sealed it. He's going to be remembered as a villain of American politics, with his 9/11 leadership only a footnote, or at least an example of how he was before he became such a monster. (Personally I hold that he always was such a monster but that wasn't the majority consensus.)
This, especially the part in parentheses
