This reads as apologia, blame-shifting, "I was just following orders".

People have to eat. They need water. They need a roof over their head. Nobody has to buy out all the veterinarians in an area at rates they can't say no to, have them sign non-competes and them jack up all the prices by 300% because, hey, you now own all of them. Nobody has to buy up all the trailer parks, which are normally peopple's last stop before being homeless, and then jack up the ground rent because, hey, where else are they going to go? Nobody has to buy up utilities, spend big on capex because legally you can pass on that charge and effectively double people's electricity bills.

Hannah Arendt coined the term "banality of evil" [1] decades ago and, in all honesty, I think it applies to the predatory nature of PE. It also goes for working for Palantir and a bunch of other companies. "I need to pay my student loans", "I'm just doing data science", "I'm just writing AI software that identifies when somebody is home" and on it goes.

PE serves no useful function in society. It's pure rent-seeking and incredibly predatory in many cases. ~15 years ago, there was a story about Goldman Sachs invented a derivative on the price of wheat and then essentially conspired to jack up the price of wheat [2]. This wasn't just manipulating a ticker on a Bloomberg terminal. It had real-world consequences. People starved and died because of this decision.

Yet I'm sure there were people who argued "I'm just doing legally allowed financial engineering here".
