Well if you support the bible then you know they exist.Didnt Jesus expel them from people?Doesnt the influence of the occult exist in music,movies and violence in the world?
Go look at a picture of Adam Lanza before he blew away 26 people a few yrs ago at the school in Ct.The look on his face is a look of evil possession.
I dont rule out someone could be mentally disturbed too from imperfection or maybe a lifelong disease taking drugs.But the bible is clear Satan and rebellious angels <demons>exist and have influenced this world.
You can also read in Genesis right before the flood how angels then were able to materialize human bodies and have sex with all the good-looking woman and they created the Nephilim...giants that were wicked in that day.
Again, file it under "Told you before" but Demons did not have sex with women. They do not have bodies of flesh and do not have the wherewithal to procreate.
But, yes, demons are quite real. Something you see regularly in the bible is the demon possessed killing themselves.(Judas, the herd of pigs, the possessed boy's father told Jesus the demon tries to kill his son by fire & water,etc) So when I see nutjobs end up killing themselves after their atrocity has been committed, I tend to think Demon possession may have been behind it.
New International Version
And the angels who did not keep their positions of authority but abandoned their proper dwelling--these he has kept in darkness, bound with everlasting chains for judgment on the great Day.Jude 1:6
File it under...why did i even bother to tell you.
Nephilim
The Nephilim /ˈnɛfɨˌlɪm/ נָפִיל, Naphíl or Naphil) were offspring of the "sons of God" and the "daughters of men" before the Deluge according to Genesis 6:4; the name is also used in reference to giants who inhabited Canaan at the time of the Israelite conquest of Canaan according to Numbers 13:33.
<yawn>its pretty cut and dry what happened here.But you keep holding fast to your Babylonish beliefs and dont heed the warning given by God to NOT share in her sins.

And the angels who did not keep their positions of authority but abandoned their proper dwelling--these he has kept in darkness, bound with everlasting chains for judgment on the great Day.Jude 1:6
Nowhere in this verse does it -even REMOTELY state- that demons took the prerogative of human flesh. You are reading into the text something that clearly wasn't stated. Some angels sided with Satan and for this, God punished them. Saying it's cut & dry is an understatement. to get any other interpretation from that verse would take a herculean effort.
Knowing what we do, "Sons of God" meant the Godly line of Seth, whose offspring were obedient to God, unlike Cain, whose decedents are the "daughters of men". Of course, I too was taught this fairy tale that demons could have sex with women & produce giants, but I actually went beyond what was spoon fed to me by unreputable sources and did a little something called STUDY. I urge you again not to take what the Watchtower tells you as fact. Use some common sense and stop being led by the nose by a known cult.
