A society filled with ruthless humans would be deadly. It's simple to forgive but some people have trained their minds to the point that if revenge isn't taken, they can never be at peace. Whenever I find myself in a position to forgive, I do so immediately even though sometimes we may have been hurt so bad but after forgiving the individual, I don't think I'll be open for him or her to walk in and hurt me again.
We do forgive but the point is some people don't learn from it, they keep repeating the same mistake without being grateful to the last forgiveness.
Yeah, things hardly remain the same, at least a dent is a must.
