Sometimes a person in a certain mood is a devil, and in another a saint. There are moods and times when a person is quite unreasonable; there are fits of goodness and fits of badness - such is human nature. Therefore one cannot say that an evil person has no good in him, nor a good person no evil. But what influences one's conscience most is one's own conception of what is right and wrong; and the next greatest influence is the conception of others. That is why a person is not free.
