I’m not sure to what extent the show wants us to sympathize with Mae. If the Jedi were somehow responsible (either directly or indirectly) for the death of all those witches, it makes it easier to sympathize with Mae’s desire for revenge. But we also see that Mae was always kind of psychotic and had severe abandonment issues: she sort of torments this small animal for fun, and then later flips out and tries to murder her sister (assuming that actually happened as depicted).
It’s the same problem with how Anakin was depicted in the Prequels. We’re supposed to sympathize at least somewhat with him before he eventually turns evil, but even early on he’s already kind of unhinged and then slaughters an entire village.
