Luckily it was only a problem in the original PS2 release where you didn’t control your other party members and could only set the type of AI they’d use. Mitsuru (who you’d almost always set on support) healing the final boss became a minor meme in the fandom.
The Persona 3 FES rerelease a year later, and all future Persona games, gave you full direct control of your entire party, so you could simply not use healing while that character was confused (which randomized the target of any actions you took). The rereleases also made the final boss way less annoying by removing its ability to act twice in a row (making it hit harder instead), so it was both a quicker fight and also much less likely you’d get hit by that spell in the first place.
If a game ever did that to me I’d probably put the whole franchise down.
