Lust for power is an idiom that describes a person who is confused by the desire for power, does whatever it takes to pursue power, disregards the interests of others, and even damages his health and personality. This kind of behavior will not only bring harm to others, but also make you feel lonely and lost. So harming others and yourself is the next sentence of power desire, which expresses that this kind of behavior will not only harm others, but also harm yourself.
