In the 4 th century church the head of Rome had a good intention. If a person wanted to have any authority or power they had to be a Christian. So in turn many evil people were placed in places of power because they lid about being of Christ. And for the next 1,000 years or more the church suffered with problems like the inquisition and the crusades. If we are really seeking God we will also seek His goodness.
Forgiveness is one of the hardest things for some to do.
Think about this, someone killed a loved one of yours and due to this you could not forgive them. As natural as it may seem, this act could separate you for eternity. But if you can not forgive, you will spend eternity separated from loved ones and in torment. If Hitler asked for forgiveness before his death, he was forgiven. Good intentions without faith in God are the paving stones in the road to Hell.
