I think that addicts are weak people.
What makes you think that they are weak?
They are good for nothing. All they do is make mistakes.
Those poor people raise themselves out of their struggles and achieve greatness. You shouldn't just put people down that are having problems. You should learn to show more empathy.
I don't need to show empathy to people that are less than me.
You can't be forced to show empathy, but no one is less than  you and you should be more mindful of the feelings of those who are struggling. You too will probably experience some forms of hardship in the future and I'd imagine you'd want others to treat you with the dignity and kindness that you deserve.
