A morality that holds need as a claim, holds emptiness-non-existence-as its standard of value; it rewards an absence, a defect: weakness, inability, incompetence, suffering, disease, disaster, the lack, the fault, the flaw-the zero.
Ayn RandWhatever may be open to disagreement, there is one act of evil that may not, the act that no man may commit against others and no man may sanction or forgive. So long as men desire to live together, no man may initiate—do you hear me? no man may start—the use of physical force against others.
