I'd never run that one until you mentioned it so I just did it via Ouro. It's a good mission, in that the story is good and coherent - it does give you a chance to feel really evilly villainous, which much redside content fails to do but yes, I found it distasteful too.
What made it worse was I was playing a demonic Demon/Thermal MM so I felt I had to take the worst options.
