We see not only how every one tries to seize from the other what he wants himself, but how often one will destroy the whole happiness or life of another for the sake of an insignificant addition to his own happiness.

Context

“But it appears most distinctly of all when any mob of men is set free from all law and order; then there shows itself at once in the distinctest form the bellum omnium contra omnes, which Hobbes has so admirably described in the first chapter De Cive. We see not only how every one tries to seize from the other what he wants himself, but how often one will destroy the whole happiness or life of another for the sake of an insignificant addition to his own happiness. This is the highest expression of egoism, the manifestations of which in this regard are only surpassed by those of actual wickedness, which seeks, quite disinterestedly, the hurt and suffering of others, without any advantage to itself.” source
