I think explaining the difference between social and non-social animals from a biological point of view might be helpful. And I would like to apologize in advance because I'm not the most organized thinker, or a very good writer.
Social animals are social because it is necessary for them to live in groups for both survival. If alone for a prolonged period of time, they will feel driven to seek it out. Isolation will cause mental and behavioral problems, and their health will be effected even if provided with all that it needs physically. Humans are social creatures. We don't leave babies alone in the NICU because it has been proven that isolation causes problems and affection actually strengthens their immune system. There have been studies that show emotionally neglected children have more sick days in school and score less on standardized tests. Prolonged solitary confinement in prisons has been deemed cruel and unusual punishment because it has such a severe effect on our psyche. Even though we have evolved as a society where you could live completely independent without needing help from others for physical survival, we still require that social interaction to be healthy and at our best. That basic biological drive is with us and drives us to seek out relationships even when we keep getting hurt by it. We can not escape this, it is a basic biological need like food and shelter.
Ever hear the saying God made babies cute so parents wouldn't throw them out the window? That's not far from the truth. When you hold a baby, both you and the infant's brain creates bonding hormones. The more holding the stronger the bond. That's why a lot of people get the baby cravings after they hold someone elses baby. In a way they're kinda going through bonding withdrawal. The parents bonding to the baby is what keeps them caring for it even when it's hard and they're putting their own health and sanity at risk. The babies and children bond to adults because it keeps them from wondering too far away before they're able to care for themselves. The same bonding hormones are produced when we have any positive interaction with others to varying degrees throughout our lives.
All that is true of all social animals. Dogs are notorious for getting separation anxiety. They are pack animals, it is not natural for them to be left alone. Although cats are thought of being very independent, they are still social animals. When they're kittens they create strong bonds with their mother and siblings. That strong family bond when they're babies allows them to bond with humans when they're on their own. They require a great deal of attention and affection in order to be healthy and happy. We don't think too much of it because the mother takes care of all that. But without it, it's one of the things that separates a domestic cat from a feral one. That early family bonding is of essential for all social animals. It's what sets them up to have healthy relationships for the rest of their lives. Without it, they will physically suffer. Even as adults they will not be as physically healthy and create lifelong mental and behavioral problems. This is true of all social animals including humans.
Now lets look at nonsocial animals. I'll use wild reptiles as an example. When it comes to families the parents are nothing but sperm and egg donors. The adults mate, then go their separate ways. The mothers lay their eggs and forget about them. The babies are independent from the day they hatch. As soon as they're able they go off to seek out their own little space in the world. If they were to wonder into their parents territory they're just as likely to be killed, maimed or eaten as any other intruder. Reptiles tend to lay very large clutches because most will not survive to sexual maturity. (social animals have a smaller number of babies because too many would put too much strain on the mother to care for them) Groups of babies without a protector is a more visible target for predators. Food is scare and competition fierce. If they were to stay together, then there would be less food to go around, making all eventually suffer. To bond with other animals, to put them first, to share limited resources would be to the determent of the health and could get them killed.
Reptiles are highly evolved creatures. They have been on this earth longer than humans and will probably still be here after we're gone because of their ability to adapt. Cold blooded animals are built to be efficient, more so than us. To even create the hormones required for bonding would be a waste of precious resources. Even if their brains were capable of making the chemicals needed for bonding the lack of a mother/child relationship would destroy that even in the most social creatures.
As you can see, socialization is a chemical/biological thing. Some animals have need of it, some do not. To expect a solitary animal to be social is no different than asking a dog to stop being a dog, a cat to do tricks on demand, or a tiger to be a house cat. You are asking them to do something they are not biologically capable and go against thousands or billions of years of instinct. We are the most evolved creatures on this planet and we can't escape our biology. It's unreasonable to expect it of the "lesser" beings if we can't do it ourselves.
