Yeah, buying out competition and lobbying to try and make your business more monopolistic is somehow a special kind of "evil" (I love moralism) and definitely not something that's allowed and actively encouraged by the system where the goal is to get as much profit as possible. But sure, it's a personal failing.

Heres a radical new idea: what if every single business owner, regardless of their wealth, is exploitative and therefore "evil" not because of their personal choices but because of how wages and profit works on a systemic basis? Workers do all the labor, the business owner gets all the value from that labor and abusing the fact that they own the means of production, they only pay workers a flat wage which is meant to merely "refresh their labor power". Its textbook exploitation and the basis for how capitalists get their wealth.

Though if you're gonna moralize capitalists, I'd argue small business owners are more "evil" than any other strata - they don't have the capital to fail and recover or start anew, so they're constantly on the verge of bankruptcy which would have their biggest fear come into fruition which is not becoming homeless, but getting a job like the rest of unwashed masses. They have legal exemptions in terms of discrimination, they're notoriously shit to work in because you get worked like a mule, and historically they've been primary supporters of Hitler, Mussolini, even Trump given their precarious economic position making them reactionary.
