He can see bad decisions, he can see the results of bad decisions, but is incapable of learning from bad decisions.
That is the definition of an addict.
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.
