I just hate it when people put blame on Satan for their mistakes instead of taking responsibility. [Spirituality & Religion]

Agreed. It's simply a scapegoat and an inability to admit to the potential evil of humanity that is inherent in everyone and the choice humans have to act that way, not the result of some supernatural force. If anything, it's a metaphor for that capacity for evil that humans have. Interesting to note that in the original story of Adam and Eve, the serpent is just a serpent and not specifically identified with any "fallen angel" or anything along those lines. That story came later.
