A few men speak with disdain over others' bad decisions. They're repulsed when they learn that a friend has sneaked back (even temporarily) into old habits. Roger visits his friends Norm and Stan for dinner and ends up drunk or smoking pot again. "He should have known better," Stan says.
Perhaps it gives the speaker a sense of superiority or he feels smug because he doesn't do those things. He can talk dismissively about others who are still caught with their addictions or weaknesses.
I think of a verse from the Bible that urges us to help those who have failed and adds, "Humbly help that person back onto the right path. And be careful not to fall into the same temptation yourself" (Galatians 6:1).
I may not have your problems, but I have my own. I'm not better than you (or worse). Each of us faces our own weaknesses.
Your addictions or problems are yours;
I must not forget that I struggle with my own issues.
