Makes no sense, how? This is a fantasy game.
Esthar feared Adel that they locked her up for such a long time. This action relied on thier belief regarding sorceresses, which is a quite harsh reason to do such a thing. There are much better alternatives than locking her up for a long time.
Would they do the same thing to Rinoa? Perhaps, seeing that Laguna is the pimp of Esthar and the father of Squall. But it's very possible that Laguna will retire his position in the future. A new president may mean a different being with a different mindset (neglecting the true feelings of connections of Rinoa and humans.) He could say "Oh, right. How wonderful of Rinoa and Squall's CO to help us." but will he sense the same feelings as Laguna? Usually, you sense strong feelings when they happen to yourself. If he does, the high chance of cards will be rolling that Esthar will never lock up another sorceress. Otherwise ...
However, if VIII is a time-compressed world, the feelings are irrelevant, and thus a different matter. Isn't it ironic how Rinoa's look didn't change when she received the powers? She didn't get imprisoned. And it's not because of the love theme. If it was, then I'd be interested to see thier design of Rinoa's "Dark Magic" look. Wait a second, that must be Ultimecia and she's already hot.
Have you ever seen the movie called Oldboy? In the end, they have changed but they still love each other.WOW! Squall is so in love with Rinoa he took a SUICIDAL jump out in to space to save her life during a Lunar Cry what DESTROYED the Lunar Space Station but he marries Ellone?
Hmmm ... You have basically posted assumptions with the aid of facts from the game. Hardly logical.I'd like to QFT here.
