[RE] Function always returns true? [closed]

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

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!!!
