The Jedi Did Nothing Wrong (except 1 thing)
Nowadays it's become "accepted wisdom" that the Jedi were this flawed organization that caused and even deserved their extinction. Some say they were dogmatic, they didn't fight for people enough (e.g. not going on a slavery-abolishing campaign on Tatooine), that they were too dumb to not allow Jedi marriage, etc.
But the truth is that none of that matters when it comes to their fall: The Jedi fell because Anakin sold them out to Palpatine for literal snake oil. End of story.
What exactly could the Jedi Council have done different? Yoda counseled Anakin on exactly what the right response to his premonitions of losing Padme: buddhist-like wisdom on not letting attachments drive you insane, and learning to let go, because there's nothing you can do about mortality... bonus, in this universe ppl just go back to the force when they die (or so Yoda said) so just accept the flow of life (unlike in our real life, where we have no f-ng idea what happens when we die or how we got here, etc)
The fact that Anakin chose to instead cling to his attachment to the degree of betraying and murdering everyone else is not a failing of the Jedi.
Neither could the Jedi have chopped Anakin's head in his sleep or such, because not only did they not know if Anakin was going to turn good or bad, but even if they knew, Jedi principles would not allow that, obviously.
Also, about the Jedi not going on slavery-eradication campaigns outside the Republic (e.g. Tatooine), they didn't have the manpower, it was too far away, and the Hutts were too entrenched... the Jedi aren't lying when they say they're not soldiers.
Also, about allowing Anakin to marry, that wouldn't have changed a thing, since that had nothing to do with his premonitions of Padme dying. It doesn't have any bearing whatsoever on Anakin sacrificing everyone else for snake oil promises for a cure.
And other arguments like, such as that.
And oh, the one thing that was REALLY weird is that they weren't fazed by the reveal of the clone army... like wtf, nobody even notices the obvious moral implications? The Jedi of all people should've been horrified at it, but even Yoda is like "well, fighting a war we are, and here they are, so use them will we I guess"
