Let's remind ourselves that being His image and likeness means being and manifesting love's ways and attributes as the material manifestation of God's love, the divine essence from which everything comes to exist. Negative traits only attract their like, and are always separated from the attributes of love which nurture all creation.
The transgression of desecrating the name of God, which also means to curse Him, makes us separate from Him and from the unity with His people. In this separation we die after our hearts are turned into stones, and these are the stones that cause our death. The choice to live ego's illusions instead of living love's attributes is the curse and the sin, and we bear their punishments.
