Why is my script not checking the characters name?

I have made a script that will check if the object that touched it is called "NPC1" or "NPC2" and then delete it.

Script:

function onTouch(hit)
	local hum = hit.Parent.Humanoid
			print (hit.Parent.Name)
			if hit.Parent.Name == "NPC1" or "NPC2" then
				hit.Parent:Destroy()
				game.Workspace.Touch.NPCSpawned.Value = false
			end
		end
script.Parent.Touched:Connect(onTouch)

But if I walk my character onto the block, it deletes my character and anyone else. The print I added was to check if the the block is getting the right object touching it and it is. I also previously tried adding a check for humanoid if statement but that didn't work.
