This person (who could be an addict or not) made a bad choice. When you make a bad choice something in your brain tells you it’s a bad choice and you respond to that accordingly. Whether you’re an addict or not you know if it’s a bad choice. If you continue down that path knowing it’s a bad choice then you’re bad. Not sick.
Look i’m not a neanderthal. I don’t condone capital punishment of any kind but in a situation like this where an idiot nearly killed a family i have zero sympathy for that idiot.
Too many people hide their bad choices behind terms like sickness. The truth is they made a bad choice and they knew it.
