"No one would have been up for that task. Maybe Master Yoda. But he had the good sense to see what I was trying to ignore."
But Obi-Wan wasn't going to argue that he shouldn't have trained Anakin. He was probably too young at the time. A newly appointed Jedi Knight, still grieving the loss of his own Master. But were it not for Obi-Wan (and his damn foolishly stubborn self) Anakin would have been back on Tatooine. Or worse. Left in the care of strangers on Coruscant, not a Jedi-in-training and still without his mother.
"Always only thinking about yourself, Anakin. There are hundreds of thousands of people being left to rot on horrible planets everywhere in the galaxy. And there are places worse than Tatooine."
They would have discovered the Sith Lord's presence. Obi-Wan had to believe that. They would have figured it out.
"You betrayed us. All of us!"
Obi-Wan's heart had broken when he'd seen the Temple recordings. Why the Younglings? Obi-Wan could understand the SandPeople. He could even come to forgive Anakin for that moment of vengeance. But the Younglings? It hurt Obi-Wan more than he could express. That he had trained Anakin so poorly that his Padawan felt he had to murder innocent children to find his power in the universe.
Maybe he had been a horrible teacher. But he would not make that mistake again.
