Even after Eden, it's very easy to blame Satan for your sins and wrong decisions. I don't dare to deny that Satan did enter into Judas Iscariot (Luke 22:3). Satan may have influenced Cain to kill Abel. Satan may have influenced the Pharaoh. But while Satan does influence certain people to sin, certain evils were also happening at the same time. While Satan is indeed powerful but he lacks omniscience, omnipotence and omnipresence because he's a fallen angel. Remember, Satan is not as powerful as God. If there's anything to blame for your wrong decisions one can take a look at the fact of one's own sinfulness. You are your own worst enemy!
In Romans 7:14-25, we read that Paul doesn't mention Satan at all when he complains about his sinfulness. Instead, Romans 7;23 says, "But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members." This is an acknowledgement that one's worst enemy is self. Satan can and will influence certain people to sin but he can't do it all at once. But people can sin even without Satan around. When Satan entered Judas Iscariot, don't tell me that every other sinful activity that wasn't recorded in the four Gospels were also Satan's doing? Certainly Satan sifted Peter like wheat but we don't see Peter blaming Satan. No, Peter just admitted his own shortcomings after he realized he denied Jesus thrice.
What I think happens is that Satan isn't necessarily there when he sins. He doesn't even know everyone sins at that place unless one of his demons tell him. But whatever sins he sees, he's simply delighted as long as it keeps the person's mind off from God. When Satan falsely accused Job, it's obvious he's not omnipresent either. Worse for him, God won't even let him do anything to a Christian without any permission. For all we know, it's one of Satan's demons roaming the area yet we can't blame the demons either. The real issue is that people sin according to their own irresponsible choices. Satan provides every falling block and sinners fall into sin by their own wrong choices. So stop blaming Satan for your sins!
