I think life is many times a "paradox", meaning its the exact opposite of what we think.
Your tying a certain set of conditions to an outcome that you want to see before you would even think of forgiving someone. I think that would keep one stuck in a judgement mentality and therefore limit ones ability to move forward.
Forgiving someone who hurt you frees you up, to move on, live the life you want, not being stuck being a referee to continue to look at the resume they bring to the table as a person then deciding if they are worthy of your forgiveness.
