Wow, I hadn’t heard that quote before but is is scary accurate and broadly applicable (think ‘psychopathic’ executives and politicians). I often wonder about those type of folks whether some transformation of mind occurs that turns a previously reasonable human being into a ‘lawnmower’, or whether they were born that way and directed their appetites into channels where they could maximise the expression of their ‘lawnmower-mess’.

EDIT: “ broadly applicable”
