Is man inherently good or inherently evil?

Mankind, like other species, is driven to survive. In order to survive, mankind performs certain critical deeds. Certain critical deeds require the destruction of other species, or require deeds that may appear hurtful or harmful to other species. Is this "evil" by definition? Whose definition? Only mankind defines "evil." Is mankind therefore a self-hating creature. Is that an inherently evil trait in and of itself? Damned sin!
