I see no difference between the evil of a murdering terrorist, to that of a wicked premeditated Trolling of a Christian community. Because both behaviors are spurred on by the enemy of God. It is zeal and passion to serve his purpose that makes the difference as pertains to escalation of animus, contempt, hatred and murderous rage.
Some such people seek to hurt peoples feelings using wicked disrespectful words. Sarcasm, demeaning name calling, etc... They intend their words to be a weapon against the emotions of the one's they target.
While the evil wicked murderous rage that picks up an actual weapon, be it a machete, a semi-automatic weapon, or they get behind the wheel of a van, or put together an explosive device, intend to hurt people for feeling a love for the Lord and joining together in worship. And as a remedy, such terrorists think if they slaughter as many as able, they'll maybe scare people out of holding faith for the consequences evil causes them to pay.
Oh, how wrong they are.
Both the murderous terrorist and the calculating community trolls. How so very wrong they are.
In this life and as they'll learn, for all eternity.
Unless or until they are able to sit aside their self-loathing first, which is what compels them to hate those who are in peace, and find the light.
God willing.
