Ethics of buying from a seller who's kicking out a tenant

[Pacifico A Comia]

Hi everyone, Im a first time home buyer, and i recently had an offer accepted on a house that im looking do a live-in flip on. I was really excited about it until I went to tour the house, and met with the tenant who currently is renting out the place. He started off by telling me how bad the house was, and how i shouldn't buy it because of all of the problems he it had, and then switched gears and started saying how he and his brother will struggle to find a place to live if i buy the place. Im really torn by this, because on one hand, I see this my first step towards financial independence, but on the other, im essentially displacing someone while taking part in the gentrification of this town.  Any advice on how to navigate morals while getting into real estate?
