Sin can't completely obliterate the image of God in man

Sin has not been so powerful that it could completely obliterate the image of God in man, but only "soil it, deform it and weaken it. It was able to wound his soul but not annihilate it. It was able to darken his intellect but not destroy it. Sin managed to open a way for hatred, but not to eliminate man's capacity for loving. It twisted man's will, but not to such an extent as to make rectification impossible" (F. Suarez). This is why, although man tends towards evil when he lets himself be led by his fallen nature, he can nevertheless, with the help of grace, overcome those disordered passions and possess and communicate to others the peace Christ won for us.

Francis Fernandez, In Conversation with God, vol. 4

This is a great reminder that to never give up, never surrender!
