Evil by choice or by Force

Some are pure evil for evil's sake but there are a few ppl I have studied Gargamel,
Khan Noonien Singh, Anikin Skywalker(Darth Vader or Lord Father) and Raistlin Majere. These ppl became evil , where claimed to be evil or to become A god. I found a M3M3 that shows Anikin watching a fire and the caption reads 'They watch the world burn to feel the warmth no one gave or let them have. they may have been fictional characters but where do these fictional characters come from written down do they do not become this or have watched in horror as family or friends spiral into Madness to be given as an Allegory Warning anything to not see good go evil . So I leave you W/this To be the E.V.I.L. evil fears and good/Godly ppl have no need of this since in the end they will eat their own the dead will burry the dead in their stomachs.
