psychologically and in fact, biologically.. the lowest-simplest-most virulent forms of life simply eat whatever, take whatever, shit where-ever.. To know this and distinguish that among other life forms, IMO is basic to self-reflective intelligence. Those individuals without critical thinking skills, on the co-dependent super-highway, that take kindness to mean "anything goes" .. are the support group for this obviously ill behavior. Incredibly fast computers and networks are the enabler.

I'd agree that there's a strong link between the selfish and the lowest, simplest, forms of life. After billions of years of evolution we really should be better.
