First hand account from someone that is actually from and lives in Brazil:

A lot of people don't like Lula because he is more left-wing and has many government policies that favors the poor, so the middle class sees that and clutches their (fake) pearls. What matters is that the majority of the population chose Lula over Bolsonaro (even of it was a tight election).

Brazil was at its peak during Lula and Dilma's administrations and at its lowest in decades during Bolsonaro's (Brazil is actually the first and only country to leave the UN' world hunger map - which happened during Dilma's administration - and return to it - which happened during Bolsonaro's).

You really shouldn't use the opinion you received from a few people from - at most - three states (of 27) in a country with over 210 million people and an area that is larger than the contiguous United States, as a measure of what Brazilians think about Lula returning. He has been back for a little more than a month and he won the elections, hence it would seem that over 50% of voter's are - at least - happier that he has returned over Bolsonaro continuing to rule.

Brazilian lawyer here:

Judge Moro was quite literally ruled biased by the Supreme Court as he and the prosecutor would literally text each other with ideas on how to best proceed to condem Lula, and Moro would give the prosecutor tips on what to file. If Lula was so corrupt and if there were so much proof against him, why would it be necessary for the judge and the prosecutor to do that?

The Court of Appeals and the Superior Court of Justice both used the cases and evidence gathered in the first degree to base their rulings, sonit really doesn't count.

Lula did indeed apoint many judges to the Supreme Court, but unlike Bolsonaro and Temer, Lula (and Dilma) always selected a candidated from a list of three that was compiled by other jurists, exactly so that whoever reaches the seat doesn't owe anything to the president and can be unbiased towards them. The whole reason that Car Wash wasn't archived the moment that it reached the Attorney General's desk is precisely because, just like Supreme Court justices, the Attorney General was always picked from such a list (that stopped with Temer and Bolsonaro, who picked people that would have their backs).

As for most corrupt: have you seen Bolsonaro's card expenses? Have you seen all of the corrupt practices that he was involved in? The guy literally delayed the purchase of COVID vaccines because he wanted to get a few dollars for each one. Hell, his whole family is involved in hundreds of corruption scandals, just a few weeks ago we learned that the former first lady had the fish from the Planalto Palace killed so that she could collect the coins that were thrown in its pond.

But even so, I'd rather have a corrupt in office than a genocidaire (especially a corrupt genocidaire)

He also got Brazil out of the UN's hunger map, Bolsonaro managed to get Brazil back on it though (first country to ever leave the map and be brought back).

She is more than qualified. Sonia Guajajara is the main name when it comes to indigenous people and the protection of the Amazon. She has held many public offices (including being a congresswoman) and this very year was chosen as one of Time Magazine's 100 most influential people. There is literally no better person to be the Minister of the Indigenous People than Sonia.

Elections in Brazil are very much safe and unrigged. We use electronic urns that can't be hacked to vote and there has never been proof of any rigging made. We even have a Tribunal that only judges on cases concerning elections.

Unfortunately it is true that some countries in Latin America, especially in Central America, have rigged elections and are under de facto dictatorships, but that really isn't our case. Elections are so important to us that we even make sure that indigenous communities in the middle of the Amazon have access to voting urns

The election was extremely tight, so there are lots of angry people here, some are even camping outside military bases asking for a military coup.

It's very similar to how it was in the US after Trump lost.

As for positive changes: Lula was president for pretty much the whole of Brazil's golden years, when 1USD was only 2BRL (its about 6BRL now), we were in the top 10 biggest economies, and huge social and welfare programs were ongoing. Lula also made sure to respect democracy and appoint people for their skill rather than to have them scratch his back later. Really hope we can get back to that and stop being the world's laughingstock.
