Touch Function going crazy?

Hello, i'm trying to make some kind of hitbox to use as a zone in a kind of Capture the zone game and when i touch it it works as expected but when i leave it it dont, when i touch it, it should add +1 to the "Hero" or "villain" value and when i leave it should negate -1 to it but what happen is it negate like -40 at once. (i left some notes bellow)

script.Parent.Touched:connect(function(hit)
	local hero = script.Parent.Hero --this is a number value
	local villain = script.Parent.Villain --^
	if hit.Name == "Torso" then
    	local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
    	if plr then
			local side = game.Lighting.Players:FindFirstChild(plr.Name).Side -- this is a string value
			if side.Value == "Hero" then
				hero.Value = hero.Value+1
			elseif side.Value == "Villain" then
				villain.Value = villain.Value+1
			end
    		script.Parent.TouchEnded:connect(function()
			local side = game.Lighting.Players:FindFirstChild(plr.Name).Side
			if side.Value == "Hero" then
				hero.Value = hero.Value-1
			elseif side.Value == "Villain" then
				villain.Value = villain.Value-1
			end
    		end)
    	end
	end
end)

You can add a Debounce to your script to prevent unnecessary firing of events.

local db = false; --It is off

script.Parent.Touched:connect(function(hit)
	if not db then --if it is off
		db = true; --turn it on, and continue w/ code
		local hero = script.Parent.Hero
		local villain = script.Parent.Villain
		if hit.Name == "Torso" then
			local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
			if plr then
				local side = game.Lighting.Players:FindFirstChild(plr.Name).Side
				if side.Value == "Hero" then
					hero.Value = hero.Value+1
				elseif side.Value == "Villain" then
					villain.Value = villain.Value+1
				end
				script.Parent.TouchEnded:connect(function()
					if db then --If it is on(like it should be if touched)
						local side = game.Lighting.Players:FindFirstChild(plr.Name).Side
						if side.Value == "Hero" then
							hero.Value = hero.Value-1
						elseif side.Value == "Villain" then
							villain.Value = villain.Value-1
						end
						db = false; --Turn back off 
					end
				end)
			end
		end
	end
end)
