I think some people put too much emphasis on Satan. We sin because we are sinners. It's not because Satan tempted us.

(James 1:13-14 NIV) When tempted, no one should say, "God is tempting me." For God cannot be tempted by evil, nor does he tempt anyone; {14} but each one is tempted when, by his own evil desire, he is dragged away and enticed.
