no - even in settings where the soul is said to be "erased" it can be returned if the writers ever felt like it, by very definition souls are completely immortal and even if they are "erased" they can return in many ways (for example Kid Buu was completely erased, yet he returned as Uub via reincarnation).

it's simply not possible for any story to have perma-death on souls, though some settings may say such - it can always be retconned.. in most setting however souls / astral energy etc can be contained infinitely via different means or exiled.

you can argue souls said to be "erased entirely" are just being exiled, souls are energy with sentience - you can not creater nor completely destroy either.. even if the writers say it is "erased".
