@pirata, Yes that is exactly where klingon culture comes from... they are supposed to be the star trek worlds "martial" culture and Japan is a prime example of that.. Its why i was happy they made klingon's "good guys" in TNG, cause I have always been a fan of martial culture's.. I really hope you have found some sort of peace with this all.. it takes time and I certainly still struggle with it from time to time, but death is not something to be feared....
Again, I have nothing to base this on, other than pure personal hope and desire, but I also believe that somethings survive death.... perhaps our strongest emotions.. thats why I try to cultivate loving relationships.. just in case
