If I ever find myself saying “if I don’t do this, somebody else will”, I don’t do the thing. It’s a good indicator that the thing in question is the wrong thing to do.
Other people will still do it. That’s true. There will always be evil people in this world. But it won’t be me. And that’s important.
Let's say we're talking about the clickbait/trolling problem in political discourse. We can berate some prominent individual, but that individual is inevitable. If she wasn't doing the clickbait, someone else would be and we'd be beratying them.
Focusing on the individual when a problem is systemic can be empty, righteous moralising.
Ethics, to me, have a place there, and it would be better in all cases to establish those rules or norms in your society, or your culture, rather than regressive actions like banning something.
In capitalism system everything is equated to money: ethics, success, self-worth.
To be exact, it is tied to short term earnings.
