By "save," what are we talking about here? Are we talking about having them be functional members of society? Are we talking about stopping them from being spergy? Are we talking about removing them from their cow status? Is it case-to-case by what the cow is known for? Because there's a stark difference between someone like Chris and someone like, say, Tariq Nasheed. They're both cows in their own right, but the circumstances of why they are ridiculed is completely different.
The title of the thread is overbroad, because if we're just talking about the concept of cows in general, then the answer is, well, it depends. I think most, if not all people have a lolcow of some sort, whether it be in real life or on the internet, whether they know the term or not. Many cows are functioning members of society, but have behaviors that make them so laughable they're a topic of gossip. If you find yourself the butt of the joke, then your only hope to be lifted from cowdom is to stop whatever is making people laugh at you. Then, I suppose, you can be "saved" from being a lolcow when people cease to have anything to milk from you.
But, if we're talking about people like Chris and other cows like him, then we get into some murky territory.
I believe that everyone can change, but the probability of it happening is dependent from person-to-person. For Chris specifically, the chances are low, and the chances of him ever escaping being a lolcow are even lower. Chris has been stuck in this mindset for several years and only proves to get worse and worse. He didn't want to change when he was still somewhat coherent, and now that he's gone off the deep end, I don't think there's any bringing him back up.
Even if by some miracle, Chris gets extensive therapy and somehow claws his way out of his delusions, even manages to contribute to society, I think people would still be on him. Even if us Kiwis don't want to interfere with him, there would still be people trying to make him relapse into his own ways. I don't think getting off the internet would even help him since most of his life is public to the world. Chris is doomed to be a cow for the rest of his life.
