【Fate】 , 【destiny】 , 【lot】 , 【portion】 , 【doom】 are comparable when they denote the state, condition, or end which is decreed for one by a higher power.
【Fate】 presupposes such a determining agent or agency as one of the ancient goddesses called Fates, the Supreme Being, or the law of necessity; the term usually suggests inevitability and, sometimes, immutability.
【Destiny】 may imply an irrevocable determination or appointment (as by the will of the gods or of God); even in this sense, however, it carries little or no suggestion of something to be feared; on the contrary, it may even imply a great or noble state or end.
【Destiny】 may also be applied to whatever one envisions as his end or goal, sometimes retaining a slight implication that it is, or has the inevitability of, the will of God.
【Lot】 and 【portion】 carry a strong implication of distribution in the decreeing of one’s 【fate】 .
【Lot】 stresses the action of blind chance or as if by determination through the casting of lots, and 【portion】 , the more or less fair apportioning of good and evil.
【Doom】 , more than any of these words, implies a final and usually an unhappy or calamitous award or 【fate】 .
