But look at the organization, not just the words: "Freeing a Soul" / "Using a Soul Coin" If using a soul coin was freeing it "freeing wouldn't need its own section.
Selflessly destroying the coin and ending the torment that the soul is experiencing is the only good act. Draining it of it vitality until it can slip between the bars is not -- not as evil as burning it in a war machine but not good either. Otherwise you wouldn't have a "Freeing a Soul" section and a "Using a Soul Coin" section. These are so evil that good characters can only bear to hold so many -- they are just worn down by hearing the screams of agony over time.
