I think Grimm are attracted to the parts of humanity that the God of Darkness put in them - destruction, negativity, etc. But because of the aspects that the God of Light gave to humanity - hope, positivity, etc - they attack. After all, the Grimm were created to destroy the God of Lights creations, and that base reason for their existence could override any companionship they may have felt towards humanity because of the God of Darkness's input.
