Keep in mind when discussing people's reactions: Roleplayers vary as much as anything else, so it's impossible to rationalize "Well, most people would feel X way about Y incident."
There's also the obvious caveat of the lalafell cult thing doing the summoning: So far we've seen summoning result in the entity being conjured on the spot. If your lalafell tribe is being held captive, there are some unanswered questions.
1) Why would Memenu leave those who summoned her in a jam to roam to Eorzea?
2) If they're not saved, and are still captured, why would they resummon her? She failed them the first time.
3) If somehow the summon didn't conjure Memenu to the summoners, how would they even know it worked? If she gets killed, how would they know to resummon her?
4) If they are saved, why would they resummon Memenu at all? Their plight is over.
