No, ill only be part of the dark side if i abuse the dark side powers, the dark side with context isnt evil. Just look at luke skywalker or obi wan
Not really, if its to protect someone or self defense, like obi wan killing general grevious, or for revenge like obi wan attempting to kill maul. But he didnt abuse the dark side.
but you choking me wouldnt fall under any of these protection of someone or self defense so your still definitely evil
