How do I get this so it stops killing the player?

I am trying to make a morph gui, I have no experience making a morph. Anyways Everytime I resize the characters torso it instantly kills the player.

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()

function onClick1()
	
	
	local rl = character.Humanoid.Parent:FindFirstChild("Right Leg")
	if rl then
		rl:Destroy()
	end
	local ll = character.Humanoid.Parent:FindFirstChild("Left Leg")
	if ll then
		ll:Destroy()
	end
	local ra = character.Humanoid.Parent:FindFirstChild("Right Arm")
	if ra then
		ra:Destroy()
	end
	local la = character.Humanoid.Parent:FindFirstChild("Left Arm")
	if la then
		la:Destroy()
	end		
	local torso = character.Humanoid.parent:FindFirstChild("Torso")
	if torso then
		torso.Size = Vector3.new(4, 3.8, 4.5)
		
	end
	
	
end
	

	
	
		

script.Parent.MouseButton1Down:connect(onClick1)

Is there a way to not kill the player?

UPDATE: I used a mesh to resize the player how I wanted, but would still like to know how to do this for the future!
