I think the most common type of evil is the wish of "want other people being the extension of someone".
It's the most common reason people want to have a baby nowadays. I think the life of many people (especially those people with baby lust) is the history of building other people as their "extension ".When they doing that, the result always fails. Until they got a baby.
The definition of "want other person being the extension of someone"is a person wants to completely manipulate the values and wishes of another person, and they don't allow the target having different ideas, usually, they want the target is the same with the control freak. This kind of evil is obvious in extreme politic groups. When a nation entering the state of war, most people would view another person is the extension of themselves in the same nation, view the successful killing as the winning of themselves. If someone says: "It's all about the military industrial complex, they are the true winners!"People would just attack this person.
Which is very horrific, for me.
If there is no war between nations, people move this kind of evil to be "baby lust" and "want to have pets(not working dogs)".Because babies and pets are the best recipients of this kind of lust, babies and pets can't talk, they are totally helpless, they can't say no, they do not have values. Before they got a baby, they must meet countless times of failure: the failure to manipulate other adults, the failure to manipulate their own romantic partners. Since babies are low efficacy extensions(as those buggy chrome extensions), they have to take a lot of time to take care of babies, but very few works babies can do. The best extension is a very very wealthy romantic partner, and completely under their control. To find out which person is most valuable, they have to show excessive enthusiasm to others for gathering personal information and emphasize external beauty since there is nothing inside them.
(sneer)They are stupid, how could be such easy? That's why they fail. After their failure to adults, they move the manipulate needs to their babies. They claim they love(I dislike to use this word) babies, but this "love" is nothing different with "I love to eat fish" since babies/fishes fulfill their needs. And then cut down the time of breastfeeding let them have tons of immune system diseases. Keeping to instill/force their values to the sick child(immune system/mental diseases) whole life to being successful for their "extensions" needs. Usually, the adult child doesn't want this.
The truth is: There is no free lunch, people having babies with purpose, the purpose was wanting cheap farm labors in thousands of years, but now, they have a new need: Since information are so easy to get, they can't build a society that everyone shares the same values, they move this kind of needs and targeted their romantic partners and children, they think they can do whatever they want to these groups and call its love.
Why they need extensions(people) in such an extreme degree? Because they know they are totally useless shit and don't want to take the responsibility for themselves as the awful Google chrome without any extensions but spying our privacy. But even Google can do the job better than them.
