Doing an "evil" playthrough atm and honestly you really do have to actively seek it out and commit to it with zero incentives. The Absolute cult is for all purposes a group of people that have been enslaved and don't realize it not to mention they'll stab you too. It also doesn't help that none of your companions really fall into the evil path. None of them make taking the evil path fun nor do any of them really rationalize doing bad things. That's the biggest issue honestly, if you're just running around being evil for the sake of evil and doing it by yourself it's a pretty limited path.
