What they learn over time isn't 'sometimes primals are okay', but rather that primals are a symptom rather than the cause, and that primals can only be appropriately handled by preventing the reasons people are summoning them in the first place. Ysayle's a big, understated part of that, essentially being the human face of primal summoners to prove to us and the Scions that they are, indeed, people.
You might have noticed that by the end of Endwalker Ifrit is no longer a problem, and the reason isn't because we murdered all his followers. It's because we have taken away the need to continue summoning Ifrit. A kind response to an unkind problem, because the Scions and the Warrior of Light are not cruel monsters.
I don't know why I'm saying this, because I fully expect your response to be ignoring this point and to instead bring up another bad faith argument that's refuted in the story itself, but there it is.
