Is there such a thing as the devil?

Well, there's no proof for such a being, and it is a Christian concept, so it really depends on your beliefs. Personally, I don't think there is. I think people use it as an excuse for bad things that happen. Humans are responsible for a lot of suffering and so humans need to take responsibility for their actions.

The Devil or Satan (with a capital "S") is a Christian invention. He or it is not mentioned anywhere in the Tanakh (OT). In fact in at least one place God himself is referred to as ha satan (little "s"). Ha satan is simply "the adversary" not a particular being. The early Christian translators seemed to think it meant a demonic being that was against God, yet in Judaism he is very much an ally of God himself.

Only in ones imagination. I believe in evil, like the young man in Charleston. The devil made me do is is nonsense. It is in some minds.

I don't know, there's a lot of people who think there is, and a lot who deny. I used to, since i'm an ex-christian, but personally over time I have seen no evidence.

. “God is a Spirit,” the Bible explains. (John 4:24) It also tells us that God made angels in spirit form. (Heb. 1:7) These are real, living persons. So the Devil, too, is a spirit person.

“But,” someone might ask, “if God made all spirit creatures, why did he create one a Devil?” Actually, God did not do so. He made all spirit creatures perfect. But one of these made a Devil out of himself. He was corrupted by his own improper desires. The Bible explains the process by which even perfect creatures can turn bad: “Each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin.”—Jas. 1:14, 15.

The improper desire that this powerful spirit creature entertained was to receive the worship of other creatures, which only the Creator, Jehovah God, deserves. He was able to get the human pair to serve him by misrepresenting to them what God had spoken about eating of a certain tree in the garden of Eden. He thus became a slanderer, or “Devil.” He is also called in the Bible “Satan,” “dragon” and “original serpent.” In time, even other spirit creatures joined Satan in rebellion against God, and also became devils or demons.—Gen. 3:1-6; Rev. 12:9; Mark 3:22.

The "Devil" is every bit a myth as his "Better Half".

The Concept is merely the "Stick" to the Carrot. It is used as a scapegoat for MANY theists who simply do not know how to OWN their mistakes.
