How can I fix this offset

So I made this script where it follows your mouse up and down.
There’s just 1 problem and it’s that the tool welded to the torso has an offset.

Footage:

Code:

local RunService = game:GetService("RunService");

local player = game:GetService("Players").LocalPlayer;
local char = script.Parent;
local cam = workspace.CurrentCamera;
local mouse = player:GetMouse();

local head = char:WaitForChild("Head");
local hum = char:WaitForChild("Humanoid");

local RA = char:WaitForChild("Right Arm");
local LA = char:WaitForChild("Left Arm");

local torso = char:WaitForChild("Torso");

local RS = torso:WaitForChild("Right Shoulder");
local LS = torso:WaitForChild("Left Shoulder");

local RSDC0 = RS.C0;
local LSDC0 = LS.C0;

local replicate = game.ReplicatedStorage.Remotes.UpdateClient;

local delta = 0;
while hum.Health > 0 do
	local tool = char:FindFirstChildOfClass("Tool");
	
	if tool then
		local x, y, z = RSDC0:ToEulerAnglesYXZ();
		local x1, y1, z1 = LSDC0:ToEulerAnglesYXZ();
		
		local r = (RSDC0 * CFrame.Angles(0, 0, -z)) * CFrame.Angles(0, 0, math.asin((mouse.Hit.p - mouse.Origin.p).unit.y));
		local l = (LSDC0 * CFrame.Angles(0, 0, -z1)) * CFrame.Angles(0, 0, math.asin((-mouse.Hit.p + mouse.Origin.p).unit.y));
		
		RS.C0 = RS.C0:Lerp(r, .25);
		LS.C0 = LS.C0:Lerp(l, .25);
		
		local m6d = tool:FindFirstChildOfClass("Script"):FindFirstChildOfClass("Motor6D");
		if m6d then
			local xx, yy, zz = m6d.Value.Value:ToEulerAnglesYXZ();
			local s = m6d.Value.Value * CFrame.Angles(0,0,zz) * CFrame.Angles(0,0,math.asin((-mouse.Hit.p + mouse.Origin.p).unit.y));
			m6d.C0 = m6d.C0:Lerp(s, .25);
		end;
		
		if delta >= .1 then
			replicate:FireServer(
				{{RS.C0:GetComponents()}},
				{{LS.C0:GetComponents()}},
				m6d and {m6d, {m6d.C0:GetComponents()}}
			);
			delta = 0;
		end;
	else
		if delta >= .1 and RS.C0 ~= RSDC0 and LS.C0 ~= LSDC0 then
			RS.C0 = RSDC0;
			LS.C0 = LSDC0;
			
			replicate:FireServer(
				{{RSDC0:GetComponents()}},
				{{LSDC0:GetComponents()}}
			);
		end;
		if delta > 500 then delta = 0; end;
	end;
	
	delta = delta + RunService.RenderStepped:Wait();
end;

Any help appreciated
