But look at Thalia before joining the Hunters. Her mom was an attention seeking crazy person, her brother was given as an offering to Hera (with Thalia never knowing what happened), was forced to run away from home, and after Hades found out about her, sent his most powerful monsters to kill her. All we see for the most part is her last stand, and she almost died. Then when she comes back to life, she finds out that one of her vest friends and possible love interests turned evil. Things didn't seem to get better for her until after she became a Hunter, which in a way makes sense. Her birth broke the pact and the reason for the pact was to prevent the Great Prophecy. Once she became a Hunter, she would no longer be the child of the prophecy so Fate has no reason to mess with her anymore.
