He should have died after that stabbing. I know y'all respectability civilty hacks hate hearing that but the danger he poses against the environment and Brazilian democracy are too high. I wouldn't be surprised if he gradually turns Brazil into a dictatorship.
If he had died that way, he would be even more deified by those who agree with him ("Myth," "Myth," "Captain") and he has 3 adult children involved in politics, now imagine if one of his sons ran for president in the future in this scenario with the argument that "They did not let my father save Brazil", would probably be elect president.
I'm from Brazil and I did not vote and I did not like that he was elected (they had several other options, in 13 candidates), but I understand that him being assassinated would only make matters much more worse.
