What worldviews deal with the topic of forgiveness?

Christianity is the only worldview that I know of that deal with the topic of forgiveness. Man is too self-centered to forgive one another. In Luke 6:37 tell us to; Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven: Since, man heart towards other are slow unless he/she is a Christ like Christian and is born again, and living to God's standards then most likely others will forgive.
