Too bad the WT didn't reverse their spiritual food in time for Chris Chavez to save his own life since this article came out after his murder. Sorry about that Chris.
Sea Breeze,
In the WT, fighting back in self defense, even inflicting a fatal blow to the assailant is permitted. at least since 1975:
Awake 1975 9/8 Page 27-28
If flight is impossible, the individual may be able to reason with the assailant. But, at other times, trying to reason with a person determined to inflict injury may lead to loss of valuable time. The situation may be such that the only thing a person can do is to use whatever is at hand to protect himself or others. As a result, the attacker may receive a fatal blow. From the Scriptural standpoint, the one acting in self-defense would not thereby incur bloodguilt.
