Shepard is dead, he or she is not watching over anyone. The 'shepard ai" even says it is based off the memories and morals of shepard. It is devoid of emotion and is following its programming. What is to stop this AI from coming to the same "logical" conclusion the starchild AI did when faced with the same problem in the future....
A few points here.
First: Shepard died, yes. Not going to argue that point, it's laid out pretty clearly. However, the Catalyst also says that Shepard's memories and thoughts will carry on, although in a different form.
There is a concept known as "consistency of thought," which essentially boils down to "it doesn't matter how, but so long as you are continuing to process new information with the same memories, experiences, and constraints any 'death' suffered is largely academic."
Shepard died, in that his/her organic mind is now ash. Shepard lived, though, in that those thoughts and memories are now shared and hosted by a series of sentient processing engines (reapers) spread across the galaxy and presumably linked via QEC. Did Shepard die? Yes. Did Shepard live? Also yes.
Shepard's died before. The ice crystal formation from water freezing in her brain would have destroyed most of her neurons, necessitating complete regrowth and regeneration. Her entire brain would need to be rebuilt - the same as it was before, yes, with the same memories, the same thought patterns, the same layout, but new cells. Did she die there? Yes. Did she also live? Yes. The memories and morals that made her who she is persisted, and even if they're being written on a "new" brain, they still work together to make the same person.
Take a hard drive out of a computer and put it in an identical copy without a drive. You'll be able to do exactly what you could before. Reaper!Shepard is Shepard taken from a Pentium 120 and put into a quad-core i7. There will be some time taken to adapt, some new capabilities discovered, but it will still be the same person.
