Hinduism vs Zoroasterianism

[WhiteWizard77]

How can the Devas of Hinduism be good, if they are the same Daevas and Divs of Zoroastrianism? Also don't you think Zoroaster was probably the right one, as he was the founder and establisher of Zoroastrianism, while Hinduism has no beginner and mostly the words of Krishna, the 8th avatar of Vishnu, are written in the Gita.

[Amor]

Deva seems to come from "from PIE root *dyeu- "to shine," in derivatives "sky, heaven, god")."

Are the shining beings the bad guys?

I do not know of a pure religion.
