I take an opposite position from most of the posters here (surprise, surprise). I don’t believe people are able to do the evil things they do unless they are demon possessed or demonically influenced. I refuse to believe the flesh is EVIL. God made us GOOD. We sin, sure- but rape, murder, torture, is a whole other level. On this level, the other human does not matter. This is satanic, when another life can be ruined. I don’t mean telling a lie or laughing at someone in public- these are sins, but not life ruining.
I am probably not explaining this correctly. I think our flesh is sinful, but not EVIL. And rapists, murderers can be rehabilitated.
My belief is this: demons are not going about doing sensational things like in the movies, throwing things around rooms and making people’s heads spin around. Satan is smart, this sort of thing does not “kill, steal, and destroy”. I think demons go about inhabiting people who rape, torture, and kill.
I don’t think we can stop demons, so it is not possible.
