The specific language "titillating and shocking" is probably used here because that's how the FCC rules are phrased. It's not just something that was made up to describe this particular scene.

Note that not all stations were fined. Those that aired the show after 10pm aren't named in the ruling.

Not to say that I agree with the FCC's standards here, but I do consider there to be a difference between showing a corpse and showing nudity. While both are a part of life, depictions of nudity and/or sexuality carry with them a certain magnetism that, for instance, a depiction of WW2 concentration camp victims does not. At least, for the vast majority of children this is the case. Expose a 10 year old to people having sex and he might start thinking about doing the same. Dead bodies, while shocking, aren't likely to get him started thinking about murdering someone.

TV standards are built such that almost anybody should be able to watch prime time programming without fear of their kid being exposed to X, Y or Z. If a particular parent is okay with their kid seeing X, Y and Z, then that's their prerogative, and they can exercise that prerogative when they rent DVDs, purchase cable programming, etc.
