Adil and Yusuf making Anime videos on Shounen Manga most of the time, such as Black Clover, Boruto, Naruto, One Piece, My Hero Academia, Attack on Titan, Jujutsu Kaisen, and more. P.s we may pronounce Japanese words wrong. lol.
The soul CAN be healed by RCT if the sorcerer is able to perceive the outline of their soul. It's a different form of RCT, but it can be done. Sukuna and Yuji are both aware of the shape of their souls, hence why Mahito was so limited against them. At present, Sukuna's RCT output is depleted, hence why he can't heal any of his injuries, whether by physical or soul damage.
