It’s considered a stable approach as long as you have maintained a constant angle glidepath. But If you are too high above the glideslope(for most runways it’s the 3:1 ratio, decent 1000ft every 3nm), there is a risk that you’ll become unstable as you fly closer to the threshold and aiming for the touchdown zone.
So it’ll be better to correct it as soon as possible so that you don’t have to risk being unstable during the last 2-3 nm with a high decent rate, and leave you with not enough room to correct and stabilized your approach.
If something doesn’t feels right, just go around. Unless you don’t care about hard landing, runway excursions or landing off the TDZ.
BTW, the accident of Asiana’s B777 at SFO was caused by a low glidepath during the final approach.
