Hadn’t considered that. You are correct, I’d agree. Addicts can see their mistakes, they are just unwilling - or lack the self-discipline to make the necessary corrections.
But, are you saying that torturing animals is an addiction?
I would classify this as a sign of a mentally defficient degenerate, a pervert, a sadist - not someone with a weak will.
People who torture animals are sociopaths and likely have addictive personalities. They may be able to refrain from their twisted behavior but I don’t know if they can change who they are on the inside.
