Everything happens in line and par with our fate. No one can conquer fate with his intelligence. Fate is the final destiny where intelligence ends and not the intermediary stage. If a man argues if fate is final why should I act will lay lazy then that is his fate and he is doomed and ruined.

The results of Man's previous births, activities decide and dominate in his next birth. God also subject to the consequences of his previous avathara activities, results. But, the difference is God takes Avathara at his own will to maintain Dharma, wherever and whenever it is threatened by wicked. Whereas man borns without knowing its purpose and its end. He does things benefiting him at the cost and hindrance of others, thereby binding himself with a long rope of papa or punya accrued entitling him rebirth.
