Not to be a Zeus defender, but I find it odd how negatively people talk about him turning Thalia into a tree, when in my opinion it's one of the best moments of his character
Like, don't get me wrong - I'm aware that, as a father, the best thing he could have done is to have saved her, the no interference in mortal affairs law be damned
But bear with me a little bit as I try to organize my thoughts
First of all, I must say: there is a law. And as much as Rick (and now a significant portion of the fandom) likes to act as if it's Zeus' law, the Olympian council, made up of 12 gods, collectively decided to put that law into place. And personally, I do think they must have had good reasons for that. Do I think some aspects of it should be revised? Yes. I don't think they should equate interference with interaction. The gods should be able to be part of their kids lives, even if they weren't allowed to solve all of their problems with a snap of fingers. But that's another talk entirely. The point is, they agreed on the non-interference law, and as their ruler, Zeus had to follow it. And I think there's something to be said about how he had to watch his kid die very, very, close to a place that was supposed to be a refuge to her, and so he chose to turn her into a tree that would offer protection for the entire camp; I mean, how many demigods were saved by this? How many gods didn't have to watch their kids die bc once they crossed that border, they were safe??
Also, to me, his decision to turn her into a tree that protected the camp demonstrates a surprising understanding of Thalia as a person, and a willingness to honour her will, because she died to protect her friends, and by creating the camp's border, he ensured that her efforts wouldn't be in vain. Every demigod in camp half-blood admires her sacrifice and is grateful for her courage, loyalty and bravery, bc that's what keeps them safe everyday. By doing that, Zeus ensured that her friends would be safe, and that Thalia would be remembered not only by the tragedy of her fate, but also by her greatest attributes.
HADES WAS THE ONE WHO SEND THE MONSTERS!!!! He was the one who killed her!! And I always thought that maybe one of the reasons why Zeus chose to turn her into a tree and stop her from actually dying and going to the underworld was so Hades wouldn't get to have her. Especially if Zeus thought he might deny her the Elysium. Or even if he just didn't want her murderer to have her soul. And honestly? That's kinda valid. To ME.
Yes, Zeus is not father of the year material. But in the first saga, it was clear to me that he cared about Thalia. He cared enough that he was willing to risk the future of the Olympus to keep her safe. Despite the fact that she was a candidate to being the child of the prophecy - a prophecy that Zeus himself would rather never come to fruition - once she was born he never tried to kill her, and instead tried to guide her to safety. He mourned her. And he cared about her! In ttc when Athena suggested that they should consider killing Thalia and Percy to stop the prophecy, he defended Thalia! He would take that risk for her!!! Yes he's an imperfect father and ruler but damn!!!!!!! HE USED TO HAVE NUANCE GUYS DO YOU REMEMBER
