The golden rule is a secular, Western value that does not seem to have curbed the violent nature of man very much.
Discussion
It may be one of an unlimited number of optional values for secular individuals.. All religion generally preaches love, compassion and anti-violent behaviour though, yet some are very poor at applying it
The commonality between our points seems to be that man is fallen and often violent, and that religion alone has not been a sufficient cure for his fallenness.
