God did read your Bible....
the same Bible also tells us where Satan is operating from.
The book of revelations makes it clear the devil was cast down...from heaven
God created the bad guy, and we're given hell of earth because of a feud. All knowing and not knowing one of his own was going to betray him and harm all he created.
What makes satan so bad if there's no account of Satan ever harming someone... Christian's God killed many and it was documented in the bible
•God takes away Adam and Eve's eternal life, thus commiting the first murder, and holds their descendants responsible and visiting Adam and Eve's punishment down on their children. In today's moral standards, the sins of the father die with the father.
•God destroys all life on Earth in a great flood, except for a drunk (Noah) and his family, for failing to worship him.
•God's tenth plague upon the Israelites was the unjustified murder of all firstborn sons in Egypt, which undoubtedly included little children.
•Before sending the plagues to Egypt, God "hardened Pharaoh's heart" so that he wouldn't let the Israelites go, so he could have an excuse to visit horrible plagues upon them, like boils, killing cattle and murdering all firstborn sons. (Exodus 4:21)
•God orders the Levites to kill their "every man and his neighnor" for worshipping another god. This cost 3000 lives. (Exodus 32:27)
•God sends a plague to the Israelites, apparently feeling that mass-butchery wasn't enough of a punishment. (Exodus 32:35)
•God kills Onan for refusing to impregnate his late brother's (whom God also slew) wife and instead "spilling his seed on the ground." (Genesis 38:8-10)
•God kills the entire populations of Soddom and Gammorah (again, including women, children and infants) for practicing certain sexual techniques.
•God gives all Philistines hemorrhoids in their pubic areas. (1 Samuel 5:9)
•God kills over 50,000 people for looking at an ark. (1 Samuel 6:19)
•God kills 70,000 people because King David decided to have a census. (1 Chronicles 21:7-14)
•God approves of slavery, and instructs owners to beat their slaves. (Proverbs 29:19)
•And, finally, God makes sure that if you are guilty of even the smallest transgression, you shall suffer endlessly for all eternity, following a dramatic homecoming for Jesus, who will be extremely pissed off at everyone for putting him to death, even though it was just the Romans and even though he
knew what was going to happen beforehand, and he could have easily avoided it by using his power as God to perform a miracle and prove who he was. (See the entire book of Revelation)
