“If I don’t sell drugs, guns etc at the street corner, someone else will. Might as well be me, I’d like to make a few hundred Billion while I am at it”

Is this a good justification though? I get what you’re saying, but the same argument you’re making for social media can also be applied to everything else, isn’t it?

If I don’t do human cloning, someone else will. If I don’t make bio weapons, someone else will. And so on
