I also think the moral ambiguity of the characters in the show is really well done... Spoiler alert for anyone who hasn't seen the first ep but is interested...

re: ImSavy saying he wouldn't do it to save anyone, the prime minister in the episode doesn't really do it for that reason either. He pretty much has the same reaction in the very beginning of the episode, which I found to be very darkly humorous. He's relieved when one of his aids tell him that he won't have any blood on his hands because of the public's sympathy for his position. Once that changes though, he has to do it, otherwise his position and the safety of himself and his family will be in danger. I thought the writing for that episode was so spot-on psychologically, really well-nuanced. He isn't portrayed as a callous jerk, nor an unrealistic Good Samaritan in the face of such an insane proposal.

I also liked the scene when he attacks that woman because that also felt incredibly realistic. It didn't feel like a scene of omg man-on-woman violence, it just felt like a genuine violent outburst from someone who is experiencing an unimaginable degree of emotional and mental stress. It's not problematic because it rings true, it feels natural. I feel like American TV would forsake that authenticity to avoid controversy, but there shouldn't be any controversy if the thing is simply done right.
