See I don't think it's about helping him at all. I think we all want to feel superior to SOMEBODY. Liberals are not allowed to be racist or prejudiced, but SMOKERS.... that's different. They deserve it. I'm better and smarter and healthier than a smoker. Smokers deserve our public derision and judgment.
My sister experiences something similar as a skin cancer patient. She lives in Southern California, often has to take a bus, and it's very difficult for her to stay out of the sun. She can't always (nor can she always afford to, as she lives on Social Security) constantly be slathering on sunscreen. So everytime she ends up back at the clinic with another spot, she gets scolded and reprimanded and lectured about sunscreen. Really? She has SKIN CANCER! Do these people think she never heard of sunscreen? They don't care about her. They just want to feel superior.
So who is the sinner to whom you feel superior?
Therefore you have no excuse, whoever you are, when you judge others; for in passing judgement on another you condemn yourself, because you, the judge, are doing the very same things. Romans 2:1
