His religion will be very cruel. Revelation
13:15 says that the image will demand to
be worshipped. And if anyone doesn't
worship the beast will be put to death.

It is terrible to even mention but a lot of
people will die during the Tribulation.

They will be executed by the guillotine
because they have not chosen to believe
and follow the Antichrist. Desparate now,
the devil will make sure that his demands
are met.
