does negative … lets call it “karma” balance out with positive “karma” (can they cancel each other out, for example), or are they entirely separate “bank accounts”, as it were? If someone does a good deed, does this good deed cancel out their bad deed?
I don’t think the show knows. All of Hook’s crimes seem to be wiped clean by the fact that he returned to SB with the stolen bean (that he stole) at the end of S2. From then on out, it’s “hero” status for him, with the exception of Dark One Hook, and despite cursing everyone to Hell, they all go to rescue him because of some perceived sacrifice. Yet Rumple sacrificing himself for the entire town doesn’t seem to make a lick of difference to the heroes in 5A when they said he had his chance for redemption and if he dies, so be it.
But I don’t know that one action cancels out the other. Saving a child from a burning room doesn’t bring back to life the child you pushed in front of a car, to get specific.
