Why can't electron vanish to NOTHING???

From Bhor to Heisenberg++, I've ever known only fact that, electron revolves around the nucleus and one attracts the other and harmony in their mobility is driven and controlled by physical laws, known with characters termed as charge and angular force specifically known to be centrifugal in nature, But what I always wonder is about the energy transfer... I've seen the physics of excitation of electron ever needs a photon and its ground state arrival releases a photon but I hardly ever found a theory or concept makes an electron completely lost itself to give nothing, I mean to say that.. an electron by acquiring energy shouldn't become beta particle, or it shouldn't become a neutron by conjunction with a proton and so on.. an electron has to die to nothing... it could be silly to visualize a fundamental particle to disintegrate and its even sillier to see that its happening towards nothing... but why is it a hard rule? that matter has to be in interdependency with energy and no dissipation of matter to zero/nothing is possible, without any conversion. Einstein may say that "nothing" is a relative term but an empirical "nothing" is always possible, which may be possible to exist in reality too. I do not even understand that why do all sacred literature of Hindu conduct, which conveys to all the world that, there exists no real death to living creatures, but souls do change their physical stature by acquiring a new body until they reach their final destination, despite lack of no known evidences for that theory, this concept says that there's a final destination to the soul that's wandering through bodies to mingle with, a big deal/big thing called super/supreme soul, after which its expected to have no integrity of its own, this at least answered a story of how soul reaches a matter of transformation without a recycle, but what's the fate of either energy that excites an electron or got released by the ground state arrival of an electron and the electron itself. There is another unlikely thing explained in the books annunciating these ideas, that the amount of energy released/under excitation and the state of excitation from ground state won't ever vary with whatever the number of times the same energy circulates through whatever the number of atoms or electron within and around its physical barriers/parameters of possibility, which contradicts with a well studied carnot cycle which explains us that "There exist no perpetual motion machine in this world", which does mean to say that the amount of energy input can't be every equal to the output called work done. Then what makes this thermodynamic based principle fail at atomic level and even deeper, or is  this thermodynamics part itself is a trash???  I want electron and so on other particles to be able to be vanished to an absolute "nothing" so that, the same process could be implemented to vanish the whole Universe, so that there won't be any autonomous chemical builds-up on the shoulders of physics with the anchor of mathematics to study its own self using a methodology called life, in the process of which it itself loses to a state of oblivion called emotions and responsibilities and so on collectively that sucks things which resemble a nonsense torturing another, where purpose is just a word.
