text: There is no Biblical reference in the Gospels of Jesus approving of killing, even in self defence he points out it isn better to be hit again than to hit back.  \nIt seems completely against the teachings of Jesus to execute another person as it is fundamentally against the idea that a person can repent sins and be forgiven.  It is also against the idea of not seeking revenge - which is the main point of execution.  And it is against the idea of "do unto others as you would have them do unto you".
