The Kim's bloodline relationship with Conviction
So we know what conviction is and does at this point in the story, with the added information that anyone can use it (but Gapryong's bloodline has an easier time using it as shown in chapter 574). But with the revelation that conviction burns up a person's everything, I wondered how Gapryong was able to use it (likely against his final confrontation with Shingen) without the backlash that he told jinrang about.
Do you think the Kim bloodline allows them to use conviction (provided they train their it and their hardware) without worrying about the backlash, unlike if anyone else were to use it, or is conviction indiscriminate in who it burns up?
