An interesting question i must say. The answer for me is YES. From my religious perspective and my faith as a Christian, I believe the life of Jesus Christ has taught us many things and most importantly the GRACE of God. You see, when Christ died for us, he showed us that even though we were sinners and all guilty, he still gave up his life to save us and has told us to love and be good to all even our enemies. So even to those who have wronged us in the past, we are called to show them the GRACE of God by being unconditionally good to them.
I know for sure it is not an easy thing to do and may look entirely stupid and unreasonable according to the wisdom of man but trust me it is more peaceful, joyful and most importantly the right thing to do. Also, if you feel they really wronged you in the past, the best way to show them the right way is not by paying evil with evil. That just makes you exactly like them amd they will see no difference in you. But when you continuously show goodness and kindness toward them, believe me that will give them no rest and they will not help but ask themselves Why are you good to them?
And that is the perfect atmosphere to win them over and show them the path of light. Take them from the darkness into the marvelous light.
Remember, we cannot conquer evil with evil, we we only end up propagating evil when we try this. We can only conquer evil with goodness and mercy. We no longer live in the era of "an eye for eye, a tooth for tooth, a life for a life" anymore. We live in the era of GRACE. Unmerited love and favour even when we are so undeserving and unworthy of it.
