"Time, I am, the destroyer of worlds." -Bhagavata Gita Assuming that you are talking about Humanity/Universe. Given enough time everything perishes. So, yes, I would agree that we are all destined to die. Personally I wouldn't want to be immortal, but I do wish sometimes I could live a bit longer out of curiosity to see how a few things play out.
Destiny is more of a predetermined set of events... Death can be predetermined to some extent because everyone of us is going to die someday. So you could say death is a part of everyone's destiny.
Destiny seems more like a goal set, its personal and subjective. Death is more like a unkown destination.
hmm... I feel if you're of a certain build then it is in your perceptive possibilities that death is a possible destiny.
What do you mean, the fat, starved, suicidal, extremeist, the patient churchy, elderly, the junkie, homeless, the insane the terminally ill?
