I can tell by your HATE that you're a christian. Being lost in hate for people you don't even know. And you think I'm the bad person here. Lol.
I've never said I didn't believe in a higher power. Not once. Oh, and, Satan and the Antichrist are Christian concepts. So, no, I don't believe God created an evil entity just so every Christian would have someone besides themselves to blame for the evil things they CHOOSE to do... they made it up centuries ago so they wouldn't have to take responsibility for their own evil actions.
But, hey, you're a good example of Christian sin, hate, judgement and antichrist behavior. Good for you.
