can i just ask would this enemy keep killing people(doing bad things)if yuna let it live?

i need to know that before i can give my answer

This is a good question. I think that the truth is they might but it isn't a certainty. The enemy is a human warrior of no great power (nothing like Sin) but has killed. I think the fundamental point here is whether Yuna would think about this "greater good" or find herself unable to act without compassion and show mercy out of what she feels morally.

It seems most people agree that she would give mercy and I suspect this myself. Be cool to see what you think

this is a vary hard question indeed and your luck i took your question ok i took this question to my final fantasy fan club at school and we came to find that we could not answer this question by just looking at yuna's character in ff10 so we went to ff10-2(now just note that i hate what square did to yuna's character in 10-2 so i only looked at key points in her personality)the yuna in ffx-2 knowing that the enemy had killed other people she would have put it to it's death but the yuna in ffx would have shown mercy so i came to the conclusion that the yuna in ffx is what i would use so here's what i think this is your story so it doesn't matter what yuna dose to the enemy it's all about your wording so to help you out i played ff10 again and choose the scenes i think that define yuna's character the most ok here they are:the boat trip from besaid to kilika just before sin's attack when yuna and tidus are talking study it carefully now next study yuna from when the party talks to lord seymour at guadosalam to when the party fights seymour at macalania temple so yes i think yuna would have shown mercy but it would be interesting to know how yuna would feel after killing the enemy

i know, she would try to convince this enemy to the good side then she would try to convince Auron to let this person into her party so she could keep a good watch over them advising on how to change... if that doesn't work... then... somebody else would kill this enemy and they would just ask her to perform the sending like in auron and Jecht's case

She is naive to a fault, however i think what she would do in this situation is free this evil person of all the pain it feels, by sending it to the farplane and wont hurt anyone anymore, even itself so id say Yuna would kill it with mercy.

yeahh she'd do the whole farplane business like the fella above said but tbh, i dont really think yuna would be strong enough in battle by herself to kill a really evil warrior, unless we're talking about when she turns 12 and gets guns in X-2...

Kill, kill, kill. Well... Maybe, I would show no mercy

We must remember that Yuna is a summoner and "sends" lost souls to the farplane. Although it might pain her, Yuna would kill as she knows that the soul, after the sending, would live on.
