Thus, any meaningful ethical dictates will come from either your whims or the group's whims or God's whims. The strangest thing of all is that the Heaven's Gate cult has been accused of selfishness. In other words, the cultists were not altruists. They even went so far as to denounce the claims that Heaven's Gate was a religion on the basis that they left no guidance for anyone to follow. The Heaven's Gate cult cant be a religion, because its just too selfish.
Religion wants to help others and is concerned with the here-after.
The cult members were not concerned with anyone but themselves. The self is, fundamentally, the mind. While they may not have been altruists in the sense that they were sacrificing themselves for us, they certainly were sacrificing themselves for some higher power, and mindlessly so. And the cultists did just this. As Im sure you all know, they had to give up all earthly possessions before they moved into Rancho Santa Fe.
