I have been wondering - for no particular reason - what is worse between being an atheist and being an idolater?
I thought that a logical place to look for an answer would be the Ten Commandments, because the first commandment is basically that Hashem is the Lord, our G-d. Ok, this emphasizes the importance of monotheism but doesn't really answer the question.
Then I looked to the Seven Laws of Noach, because they were meant for the whole world, not just Jews. The first law is "Do not deny G-d", but this could mean "don't deny there's a G-d" as well as "don't believe there are many G-ds".
Trying to recall about something in the Torah that would answer my question I thought of Abraham. He convinced people there was a G-d and he also smashed idols (according to the Midrash). Realizing this still didn't explain my doubt, I ask here, what is worse? Believing in many G-ds or not believing in G-d at all.
