Condemning Others to Hell

If you are asking if a person can condemn another person to hell through recourse to a satanic act, the answer is no. All who go to hell go there by their own free choice. That said, to try to condemn another person to hell through recourse to satanic acts is grave matter. If done with full knowledge and deliberate consent, it would be a mortal sin. If someone dies without repenting his mortal sins, he himself will go to hell.
