Human society and life isn't one of cooperation and harmony, it's a competition and we're all striving to one up each other to varying degrees. If that involves literally kicking another guy off the ladder, so be it. If a cop is feeling particularly irate and/or is hard pressed to satisfy a quota with frivolous speeding tickets, so be it. Contractors inflating their hours is par for the course.
Life ain't all sunshine and flowers, it's also dirty and ruthless. Nobody's a saint in this plane of existence.
