[RE] Function always returns true?

reposted because no one answered first one rip me

I made a camera, For my training game. Now, Hear me out, I am not good at making scripts tidy. What the problem is though: This function always prints true now matter what:

function IsPlrIgnored(HRPN)
	for i,v in pairs(PLRS) do 
		if HRPN == v then
			print(v)
			return false
		end
	end
	return true
end

I implemented this for a bug. Its a weird bug, When two players stand next to eachother, One in the group and not in the group, The camera will target the player in the group. This is not what i want. This happens randomly. Idk what to do. Can someone fix this VERY broken script?

local RS = game:GetService("ReplicatedStorage")
local RS2 = game:GetService("RunService")
local DB = false

local Barrel = script.Parent
local Decal = Barrel.Parent.Parent.Screen.Screen.Decal
local CON = script.Parent.Parent.Configuration

local fireRate = CON.Rate.Value
local aggroDist = CON.DetectionDistance.Value
local IgnoreList = {Barrel}
PLRS = {}
--------------------------------
wait(3)
function checkIfInGroupAndGroupRank(PLR)
	if PLR then
		if PLR:IsInGroup(CON.Group.Value) and CON.Group.Value ~= 0 then
			if PLR:GetRankInGroup(CON.Group.Value) > CON.GroupRank.Value and CON.GroupRank.Value ~= 0 then
				print("True")
				return true
			end
		end
	end
	print("False")
	return false
end

function checkIfInGroupAndGroupRankAll()
	for i,v in pairs(game.Players:GetChildren()) do
		local iigagr = checkIfInGroupAndGroupRank(v)
		if iigagr == false then
			table.insert(PLRS, v)
		end
	end
end

function IsPlrIgnored(HRPN)
	for i,v in pairs(PLRS) do 
		if HRPN == v then
			print(v)
			return false
		end
	end
	return true
end

checkIfInGroupAndGroupRankAll()
--------------------------------
while wait(fireRate) do
	wait()
	script.Parent.Mesh.TextureId = "http://www.roblox.com/asset/?id=2093097"
	Decal.Transparency = 0
	local target = nil
	for i, v in pairs(game.Workspace:GetChildren()) do
		local human = v:FindFirstChild("Humanoid")
		HRP = v:FindFirstChild("HumanoidRootPart")
		if human and HRP and human.Health > 0 then
			if (HRP.Position - Barrel.Position).magnitude < aggroDist then
				local ray = Ray.new(Barrel.Position, (HRP.Position - Barrel.Position).Unit * aggroDist)
				local hit, Position = game.Workspace:FindPartOnRayWithIgnoreList(ray , IgnoreList)
				if hit.Parent == human.Parent or hit.Parent.Parent == human.Parent then
					target = HRP
				else
--					print("Blocked "..hit.Name)
				end
				if hit.Transparency == 1 then
					table.insert(IgnoreList, hit)
				end
			end
		end
	end
	if target then
		print(target.Parent.Name)
		local IsPlrIgnored1 = IsPlrIgnored(target.Parent.Name)
		print(IsPlrIgnored1)
		if IsPlrIgnored1 == true then
			local HRP = target
			Decal.Transparency = 1
			script.Parent.Mesh.TextureId = "http://www.roblox.com/asset/?id=4989331700"
			Barrel.CFrame = CFrame.new(Barrel.Position, HRP.Position)
		end
	end
end

REMEMBER: No errors in output and, MAKE A GOOD ANSWER! Tell me why, How to prevent this kind of stuff happening, AND FIRST LOOKING AT THE QUESTION!!!
