Also Scorpion and i am sure that you know this,
Once someone receives the mark, they are Slaves to Satan. It is written that all who receive it is condemned. Anyone who has this mark within them are literally slaves to Satan, their mind and body is controlled by the beasts. I find it rather odd that in science fiction movies where aliens control human beings through mind control, well..... lets just say that it's not too far off. But in this case these otherworldly beings{Demons} will literally possess those who have the mark through demonic technology.
God Bless!
