Have you watched TCW? Yoda has plenty of emotional attachments. We literally see them, in his head. During Order 66, he reacts on an emotional level to the death of his fellow Jedi. The idea of no emotional attachment is a lie. They can't pull it off. A Jedi would have to lack empathy to pull it off. Yoda, Obi-Wan, Qui-Gon, Ahsoka, Luke, Rey, Kanan, Ezra, and every major Jedi we have known, has emotional attachments. You know who doesn't?
When Satine died, Obi-Wan didn't fall to the dark side, not because he wasn't emotionally attached to her. He loved her. It's why he always came calling in her time of need. He doesn't fall because he doesn't give into his hate. The Jedi are in a constant battle against the dark side, even inside themselves. That's what makes them Jedi.
