Gabriel is not actually trying to break Adrien's curse, and is the one who cursed him in the first place.
- Despite working on it for years, there hasn't been any progress in breaking the curse. He's also never tried to contact a specialist, who would have a much higher chance of succeeding.
- It's mentioned that the curse is layered, which could mean that instead of trying to break it, he's actually reinforcing it, since a layered curse would likely require repeated casting.
- Considering how he treats Adrien in general, it's not much of a stretch to assume that he would deliberately curse his son in order to keep him as isolated as possible.
