Yeah you can do that.
Certain bindings are meant to target physical feelings. Some more mental, some more emotional. Etc.
So if you have a binding meant to make you feel what another person is feeling for example and a curse is making them feel awful then even if you aren’t cursed, you’re also feeling awful. When binding, it’s important to take degree into account, what percent of what the other person feels do you also want to feel.
So if you’re in charge of binding two people and you want them both fucked, then make sure they’re both suffering the same shit. Might not manifest exactly the same in them, but it should be pretty close. If they’re both cursed and one uncrosses then how cursed they still are depends on the person who cursed them, the uncross-er, and the person who bound them.
If the uncrossing is stronger than the curse, it’s possible the curse will be completely gone. But what’s more likely (if the person who bound them is any good) is that while one person will be uncrossed in name, both bound people will still be experiencing symptoms as one of them who was originally cursed is still cursed.
If that doesn’t make sense I can try again.
