I believe so. Purity of heart is cultivating authentic “goodness.” That is, doing the “right thing” for the sake of the thing, not for reward or recognition, although that may be a by-product. Not necessarily “right” by social standards, while also recognizing that what is right for you may not be, for someone else. I noticed you said later you hold a Christian perspective. Jesus said the well don’t need doctors. He was a champion of the poor, outcast, and women. He forgave what temple authority wouldn’t. He interceded for his murderers. I would also refer you to the 51 Psalm.
