The Jedi are so needlessly neglectful towards Anakin in their attempt to try to teach him to be emotionally detached, and then they wonder why he became loyal to the only guy who would actually listen to him (even if it was just to use him).
That is why Anikin was too old to be trained as a Jedi. Not because he was too old to learn how to fight, but because he was too old to be brainwashed to be a warrior monk. He had ties to the outside world. If they had started his training at birth, he would have no worldly ties to hold him back.
And before anyone calls me out on it, I have not consumed any Star Wars media other than the first 6 movies. I am well aware that I am pulling lore out of my butt.
The jedi are so colossally ignorant it's sometimes funny. They, in the height of their power during the new republic, sought to fulfill a prophecy that would bring balance to the force. My dudes, the scale is so heavily tipped in your favor what the fuck do you think is going to happen?
Actually the council decided not to, but qui-gon, the grayest motherfucker there, decided to do it anyway. Maybe there was some intent there?
Quigon trusted the force. There were 2 paths, and he hoped for the one that didn't come to pass. And then he trusted that Obiwan would be able to stand in for him if he needed to.
The most damning thing he ever said was 'you were my brother Anakin. I loved you.' Because a brother was not what Anakin needed.
But, you know what, I blame the whole thing on Yoda. One kind word from Yoda. One reassurance from this being who had lived so long in the world he literally had no right to not have god like wisdom, and it all would have been averted. So many possible off ramps and they failed anakin at every turn. It's the most tragic story ever.
Further, one could argue that he did have those same exact issues, despite an almost "best" case scenario at the time Yoda brought it up, as it relates to this issue: the only family he knew was killed on the farm, his best friend from his past life was killed in the Death Star battle, his mentor and teacher was killed escaping from the death star, and he had no idea who his father really was or that his sister even existed.
The only major attachments he'd formed that could still be used against him and his training were those he'd made to his friends, and to a lesser extent, his cause.
And what happened?
As soon as his powers were trained to the point that he could reach out with his feelings and sense (and be sensed) across the wider galaxy, literally as soon as he gets to that level, the Sith use it as a weapon, and manipulate him using his few attachments, lure him away from his training and out of hiding and indeed directly to Vader, who then puts another barb of attachment into him by revealing his ancestry.
Had Vader not had the dual "failure" of both trying to recruit his son against the emperor and then later turning on the emperor (and of course, Palpatine's arrogance in underestimating both Luke's resolve and Vader's attachment), the plan would have absolutely worked, dooming the Jedi and the Alliance in one fell swoop.
Like...not only is Luke not a great case for "age doesn't matter", he's very nearly the poster child for why it does.
Because I believe I'm right and that it adds something to the discussion but if someone is passionate enough to write a 5 paragraph rant on why they think I'm wrong it's definitely not worth my time to argue with them.
Because the jedi aren't the good guys. I've said it for years they're designed as the righteous side of the same coin of the Sith. Always rambling about balance and such then willingly submitting as the lapdog police force of the bloated and corrupt Republic, only taking action when their masters need a war. It's thousands of years of moral objectivity gone wrong through the eyes of dogma fanatics who've lost their way.
Even Luke's revival (fuck off Disney) is bound to fail.
