That Time I Got Reincarnated as a Slime: Tensei shitara Slime datta Ken

As it is, Rimuru himself couldn't even have done the resurrection. It was stated in the scene that it required an enormous amount of control over the colossal amount of magicules. You could basically say Raphael is like an AI run by a supercomputer, able to perform bazillion flops.

Which is all well and good. But this is fiction. And AI in fiction almost always goes bad at some point. And an unfeeling AI with Rimuru's power at their fingertips could go very bad indeed.

Either the resurrection would be nothing much, nothing special, or Rimuru's character would be half-assed because when you look at Raphael, or the predecessor Great Sage, it's kind of an impersonal entity, indeed like an AI. So, if Rimuru himself was capable of the same, it would mean Rimuru ought to be like that as well. It could be quite a sucky MC.

I dunno. You're basically describing Senku from Dr. Stone. He can be impersonal and calculating when he needs to, but he can also be very compassionate when he wants.

And obviously, he summoned 3 demons and the other 2 demons are there just for the sacrifice?
It's kinda pointless to include them in this show, so I guess, since they sacrificed themselves and to give these other two demons a reason to exist in this show, everyone who died and ressurected by their sacrifice, is now stronger than before and stronger than they would have been with the additional "gifts" from Rimuru's ascension.

Agreed. Unless this is setting something up, it was just wasting the audiences time. Have just one demon show up and then don't have the manufactured tension of there not being enough magicules if it's going to be solved immediately by sacrificing characters we have no attachment to.
