In what form... ?
Who or what is evil in your opinion ?
ha ha ha. Good one. Well i am less inclined to dwell on demons and connections to supernatural events because i just dont feel it anymore. At one time i thought that maybe i would get a definitive answer but now i just feel that if they wanted us to know than they would be more obvious about it. And TBH, all my research has been pretty meaningless but i am conscious not to cross any lines or open up the wrong door.
In relation to manifestations of evil pertaining to human behavior:
This is a much more difficult call.
Although this ghost video has been widely viewed perhap you have not seen it:

The first time i watched it i was pretty impressed bu then when i watched it on youtube i was able to pause it and i think you see where the frame of old lady pops in. So if you were to go frame by frame you would see the image pop in more clearly but then on the other hand perhaps i am seeinfg it worng...you cannot go frame by frame in yourube.
Fake or NOT?
Be that as it may, i can see a relationship between evil and ghosts.
Now if there are ghosts, and i can say that a few times i have exoperienced a presence. One time it came and sat at the foot of my bed and another time i was roughed up a bit. Sat on my chest and scratched my leg with its sharp nails. Also, my mouth filled up with blood, i coud taste that rustly bllod taste as i struggled to be released. That was scary. And the bad part is that I dont know if i was dreaming or if it was real because it comes right at that time when you are dozing off and if you try...ah, i shoudnt say anymore but perhaps you have called up them yourself. Like i said, luckily this does not happen anymore but and if anythbing i have lost the ability to manifest (call) an entity, they left hanging around me or it is in remission.
In summation, there is a good chance evil exists.
Maybe later on we can discuss evil more in depth but this is a little touchy too too far into.
