Does devil worship really exist?

Superstitions exist, but they are not real.
Only the Cause of God is real through all time and space.

I guess if you believe there is an ultimate good (god etc) then there has to be an ultimate evil.( the devil etc)

What is humourous is that the devil is part of the christian mythos...so for someone to worship him...they are actually Christians.

Yes there are those that honestly do devil worship, and or worship of some ancient babylonian gods...eg: Molech. Google Bohemian Grove, where high powered executives and politicians meet every july. They dress up in KKK robes and perform a "mock sacrifice" of an infant. It is called the "Cremation of Care" ceremony. Even if you do not belive in the devil, understand that there are psychos running things that DO.

Yes, Satanic worship goes on every day in many areas of the world, especially in the US. Police records indicate, though they often don't go public, that satanic worship is off the charts in high schools.
Whether they are worshipping the real satan or just the ideals of what he stands for makes no difference because both sects are dabbling in a very real demonic pot of stew.

satan is very real and so are his angels (demons). His purpose is to be like God, to be exalted and worshipped. He promises power, pleasure, and indulgence to lure many into worshipping him. The trouble though is that many more are worshipping him without even giving him any thought.
He seeks to inundate people with everything their heart could posibbly desire in an effort to keep them blinded to God. Satan is the ruler of this age and we see him manifesting himself today like never before. But his reign of terror is about to come to a screeching end as the King of Glory, the Lord of Hosts, the Alpha and Omega- Jesus Christ is returning to judge the nations and satan, along with all of those who chose him to be their god.
Get right with the Lord today. He died that you would not forever belong to satan. And it is by Christ's blood alone which you may be saved.

Nah it does
Or at least ppl try to
Hopefully they are not doing it right

it's about as real and stupid as God worship imo...

I don't think so...

It does exist, it's just not popular.

That is whats called 'Theistic Satanism'. Theistic satanists often believe in the devil, and partake in sacrifices and such.

But another type of satanism called 'LaVeyan Satanism' or 'Philosophic Satanism' just mainly promotes ideals and morals opposite the Christian set, rather than actual Devil Worship.

Yes

Yes!
