Satan is not around today, due to the Bible proclaiming that he is done away. Just remember that darkness does remain and all us have a choie to partake of the tree of the knowledge of good and evil, or partake of the tree of life, (death, burial, and resurrection.)
If you believe Satan is still around that is okay, however I do not believe he is still around, and put the main responsibility of actions for individuals upon themselves. From within the soul, we control this body, and from within the soul can come darkness, just as Jesus foretold.
Mark 7:21 For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, 22 coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. 23 All these evil things come from within, and they defile a person.”
