You don’t understand demons and how they work. Demons can make you do almost anything if you don’t know Jesus. They look for a weak spot and move in. Islam is the religion Satan uses to sanctify murder and violence. If you give your life over to Satan’s religion, you will have signs of insanity. The demons keep you from a right mind until they destroy your life. Same with drugs and alcohol. Tell them to stop, beg them, even while they are in the ER almost dying and they come back to the demon. You can’t reason with them because they can only hear and obey the demon speaking in their head. Jesus is the only one I’ve seen able to set men free. If you go to battle unarmed, you will lose.
I’ll grant you I’m a bit rusty on demonology and i didnt go to medical school, but I do know a tiny bit about brain tumors. A loving and kind uncle became a raging monster over a period of about four months. Luckily, if that’s the right word, he had a mild heart attack and a complete work up led the docs to discover the tumor. He recovered and, while he lost a bit of mental acuity, he was his old self again. My aunt was the saint in all this sticking with him.
