and thus it is, that every man, in the state of nature, has a power to kill a murderer, both to deter others from doing the like injury, which no reparation can compensate, by the examle of the punishment that attends it from every body,
and also to secure men from the attempts of a criminal, who having renounced reason, the common rule and measure God hath given to mankind, hath, by the unjust violence and slaughter he hath committed upon one,
declared war against all mankind, and therefore may be destroyed as a lion or a tyger, one of those wild savage beasts, with whom men can have no society nor security:
And Cain was so fully convinced, that every one had a right to destroy such a criminal, that after the murder of his brother, he cries out, Every one that findeth me, shall slay me; so plain was it writ in the hearts of all mankind.
