The Bible tells us not to have anything to do with the devil and if something like this causes your thoughts to turn toward him, or it deceives you into thinking he isn't really evil, then you should stay away from it. The Bible says, "Avoid every kind of evil" (1 Thessalonians 5:22).
Never forget: Satan is absolutely opposed to God. His sole purpose is to block what God is doing including what He is doing in your life. One of the signs that God is working in your life is that you have become sensitive to things like this, and Satan would like nothing better than for you to ignore what God is trying to tell you, or to laugh it all off as harmless. The Bible says, "Resist the devil, and he will flee from you. Come near to God and he will come near to you" (James 4:7-8).
I'm thankful you have given your life to Christ and now I pray you will grow in your relationship to Him. Take time every day even if it's only a few minutes at first to be alone with God, reading from the Bible and bringing every concern to Him in prayer.
In addition, if you haven't already done so, ask God to help you find a church where Christ is preached and you can grow spiritually. You'll also find other believers there who have faced the same questions you are facing and can help you.
