Frisk's resistance to soul manipulation

[Armormakes]

How does Frisk have resistance to soul manipulation. I get that they don't instantly die from a hit to the soul, but the monsters change the properties of Frisk's soul all the time, (Papyrus, Undyne, Muffet, Alphys, Sans). Frisk shows that they can't resist the changes to their soul so Frisk should have minor resistance to soul manipulation, not complete resistance.

@Armormakes, normally if a character don't have Soul Manipulation Resistance then it Soul Manipulation, behaves like Durability Negation. Frisk does resist the soul damage as normal damage then he/she can heal.

Other character in Undertale have minor resistance because of the same thing as Frisk. I don't see why he is an exception.

I get your point about frisk taking soul damage as normal damage but they still get their souls properties changed by bosses. I'm not completely sure how that would work if frisk had soul manipulation resistance as their soul is changing throughout the fight.
