Does Jesus consider Atheism, and other religions to be the greatest sin?

[ChristJudgeOfAll]

Jesus said

The greatest commandment was: Hear, O Israel! The Lord our God, The Lord is One; Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.

And in accordance with the old testament: "Thou shall have no other gods"

Does this mean, that atheism, and people of other religions aside from the Christian faith are worse than murders, rapists, and other sins?

No, the specific sin doesn't matter. Sin is sin. If you are saved then you are cleansed of all sin. If you aren't saved then even one sin is too many

If there are greater or lesser commandments though, wouldn't violating a higher ranked commandment be worse?
