Saint Francis- He saw nature as God's masterpiece and loved animals. "If you have men who will exclude any of God's creatures from the shelter of compassion and pity, you will have men who will deal likewise with their fellow men." ~Francis of Assisi
Forgive them even if they are not sorry. One thing I learned in life is forgiveness. It doesn't mean what someone did was ok, it just means that I was able to release all the negative feelings I had towards that person.
