You are wrong my raakshasa friend
Dasyu doesn't mean atheist. The word दस्यु has its root as दसु उपक्षये Giving its deravative meaning Yaskaracharya writes in Nirukta (7.23) He is Dasyu who has very few virtues n who causes obstruction to good actions like the Yajnas.

Dasyu has been stated as one who is dacoit, a thief, on betrayer of confidence, foolish, licentious, aggressor, obstructor of good deeds, selfish etc. 
In Rigveda l.ll7.3 ऋषिं नरावंहस: पाञ्चजन्यमृबीसादत्रिं मुञ्चथो गणेन। मिनन्ता दस्योरशिवस्य माया अनुपूर्वं वृषणा चोदयन्ता ॥ The adjective used for Dasyus is आशिवस्व (who creates trouble and causes misery).
In short Dasyu denotes unscrupulous people with criminal tendencies.
