You should not call normie NPCs sheep as its offensive to sheep.

I work with sheep and know a bit about them.

Sheep fight back.

Sheep strain when under stress.

Sheep will shun and ostracize the ill/sick.

Sheep will respect you if you are "alpha" (ie strong and focused" when shearing them.

Sheep sometimes want to hurt those handling them.

Normie NPCs do none of this.

They are drones with no personality, fight, morals, common sense, or respect.
