Free Will, Determinism or. Compatibilism?

I’m relatively new to the forum so apologies in advance if I may be repeating a thread that already exists elsewhere. The reason I‘m starting this thread is to get a view on the Epicurean position on free will. The general sense I get is that the Epicurean stance is one of compatibilism, i.e. some things happen deterministically while other happen out of free will. Is this understanding of the Epicurean stance correct? I’d also be curious about the ethical implications of this view. Any guidance is much appreciated 🙂.
