After clarification from the mods, if this is the more realistic/plausible "let's NOT kill the goddesses" option, Edna would be on board - she at the very least would want to hear how the goddesses feel and their opinion, on how their existence is causing the destruction of their own world. It ended up hitting a little close to home after all, that their death may seemingly be the only option for 'salvation' (and it wouldn't be the fairest thing either, ALASTAIR playing judge/jury/executioner without the locals being potentially any wiser).
