Context

“(for he will both himself profit by doing noble acts, and will benefit his fellows) , but the wicked man should not; for he will hurt both himself and his neighbours, following as he does evil passions. For the wicked man, what he does clashes with what he ought to do, but what the good man ought to do he does; for reason in each of its possessors chooses what is best for itself, and the good man obeys his reason. It is true of the good man too that he does many acts for the sake of his friends and his country, and if necessary dies for them;” source
