However, Madam Red was able to see Grell just fine during the Ripper arc, and during the Campagnia arc, all the various human characters we see clearly had no issue seeing any of them.

If I recall correctly, in the manga chapter in which Ciel and Sebastian spot the German shinigami Sascha and Ludger, they mention that it's unusual for humans to be able to see shinigami.

If there was a higher up trying to force her, she would've easily been able to get out of having to operate simply by threatening to report said higher up to the authorities.

But it was outright illegal, with a possible punishment of life imprisonment.

Could be someone higher up giving the order to go ahead-if Angelina was just the surgeon, she might not have a say in who does or does not get a certain operation.

(If anything, those operations likely would've ruined her reputation and her career if word had gotten out about them.) Did Angelina have a desire to help her patients regardless of the problem, but her feelings twisted into resentment later on? Or is it a mistake?

If she hated it so much, why on Earth did Madam Red give abortions to those sex workers? It was illegal at the time so it's not like her career would've taken a hit.

Other than 'because plot', if Claude wanted Ciel's soul so badly why didn't he just try to take it from Sebastian, like he already had done prior to the beginning of the season? It's not like demons and humans need to have a contract for the former to be able to eat the latter's soul.That said, the terms of the last order included that Sebastian would serve Ciel until he consumes Ciel's soul, and since he now has no soul to be eaten Sebastian is now stuck forever unless he wants say 'screw it' to his aesthetics.

Not going to lie, that is weird and if he wanted to Sebastian could really attempt to kill Demon!Ciel, especially since Ciel shouldn't have the experience to properly defend himself.
