These kinds of claims generally come from people who don't feel any moral or ethical impulses. These people are most commonly malignant narcissists and psychopaths. A great example is Elon Musk who described empathy as a "bug".
Morality is a fundamental feature for most humans. The people who make the kinds of claims above constitute a small, single digit percentage of the population. They tend to have an outsize influence though, because they exploit the trust of others to rise to positions of power, where their lack of compunction can be an advantage.
People like Trump, Musk, and Thiel are canonical examples of this. Eventually, when their actions make things bad enough for everyone else, people tend to take action. We may be approaching a time like that. You acknowledged this yourself in earlier comments.
