Just a bit of lone Lucy for this one, since there's something about morally-questionably Lucy that I find interesting.
Venal
"Originating in, characterised by, or associated with corrupt bribery."
Lucy had always liked her job. She'd always loved the feeling she got from knowing she was helping her community and making it a better place. But, she also liked being able to pay her bills, and she couldn't really deny that she liked the idea of having someone looking out for her back, even if the people who did weren't the most upstanding citizens.
When she'd first joined the force, Lucy had hated the people who were swayed by money. It was part of why she'd joined the force as it was; she'd been sick and tired of seeing the ones who were supposed to uphold the laws they abide by just turn a blind eye to the dealings around them. Lucy had wanted to change that.
Lucy hadn't meant to become the people she hated, though. But she'd befriended the wrong person, let herself by used, even, and before long it had been too late to get out. She'd become the type of person she'd hated most, corrupt and venal and looking the other way for the sake of her own comfort.
Even years later, Lucy couldn't help but feel ill every time she paid a bill or even bought something she wouldn't have otherwise been able to afford. But doing the right thing wasn't an option anymore.
