Answer:
Both state that each individual has free will to do good or evil.
Step-by-step explanation:
As Judaism and Zoroastrianism are both monotheistic religions and are both part of the oldest religions on human history, both state a inner struggle within the human to do good and evil, Zoroastrianism takes it even further and believes in the general good vs evil struggle in the whole cosmos that will eventually be won by the good and thus detroying the evil that exists in the world, kind of like what the judaism beliefs with the second coming of God.
