Why aren't my npcs killing everyone?

My npcs are supposed to move and kill other people/npcs but after they kill 1 dummy the won’t move anymore. They also won’t target players, only the dummy. Does anyone here know what’s wrong with my script?

ServerScript: --placed inside the model of npc

local RomanRoot = script.Parent.HumanoidRootPart
local RomanHumanoid = script.Parent.Humanoid
local Model = script.Parent
local ss = game:GetService("ServerStorage")
local collectionService = game:GetService("CollectionService")


while wait() do
	
	
	local function findenemy()
	local aggro = 6000
	local target = nil
	local dmgrange = 7
	for i, v in pairs(game.Workspace:GetChildren()) do
		
		if collectionService:HasTag(v.Parent, "Iskandar") then
			print(v.Parent.Name)
			return
		else do
				
				local human = v:FindFirstChild("Humanoid")
		local root = v:FindFirstChild("HumanoidRootPart")
		if human and root and v ~= script.Parent then
		
					if v.Humanoid.Health > 0 then
						
						if v.Name ~= "RomanSoldier" then
			if (RomanRoot.Position - root.Position).Magnitude < aggro then
				aggro = (RomanRoot.Position - root.Position).Magnitude
				target = root
				if (RomanRoot.Position - root.Position).Magnitude <= dmgrange then
						human.Health = human.Health - 15
					end
				end
			end
		end
		return target			
	end
end
						
		end						
	end
end
			
				
		 
		
while wait(1) do
	local torso = findenemy()
	if torso then
		RomanHumanoid:MoveTo(torso.Position)	
	end
	
end
	
end

You have your while wait() do before your while wait(1) do so it will never execute findenemy()
