I said it seems that people play common roles to circumscribe and safeguard against being insane. This means: essence is undeveloped, so personality needs to cover it, surround it, to protect it. It's a weakness because undeveloped essence is, well, being in a state of undevelopment. This is why it's comical to get angry at human beings. It's like getting angry at a machine. (Machine? Where have I heard that terminology before?)
Essence, when undeveloped, basically operates in the world like if you have a mental problem, or an assortment of them. Or if you are just like a puppy. Or, you know, whatever. Maybe something very negative and violent. Also, one has to add that evil spirits probably possess people who have no protective shell of personality. Or can. So there is that element in the population too. In Hades this is the chaos going on.
This is not an exact science. Of course.
Another thought: probably when you fall in love with a person, or are just fond of them, it may be little insights into their essence that you've come to see or connect with. Maybe. Something that distinguishes them apart from the machine that they are otherwise.
