Yes. The only thing Hallow prevents is damage, and Supreme Verdict doesn't deal any.
Damage
Objects can deal “damage” to creatures, planeswalkers, and players. This is generally detrimental to the object or player that receives that damage. See rule 120, “Damage.”
120. Damage
120.1. Objects can deal damage to creatures, planeswalkers, and players. This is generally detrimental to the object or player that receives that damage. An object that deals damage is the source of that damage.
120.1a Damage can’t be dealt to an object that’s neither a creature nor a planeswalker.
120.2. Any object can deal damage.
120.2a Damage may be dealt as a result of combat. Each attacking and blocking creature deals combat damage equal to its power during the combat damage step.
120.2b Damage may be dealt as an effect of a spell or ability. The spell or ability will specify which object deals that damage.

Do all my creatures die ??
