I know after a decade+ of mainstream culture shitting on people for what they do outside of their professional capacity this is going to seem like an odd opinion but doing bad things and/or having moral failings outside of the specifics of work does not preclude being good at one's job.
How do you think all those wife beating cops everyone talks about manage to stay employed? They do their jobs.
All those commies that McCarthy said infiltrated industry, how did they get there? They did their jobs.
Alan Turning's "moral failings" were so bad he was criminally convicted for them yet he did some of the highest quality work in his field.
Etc. etc.
