Why do people assume that Reghabi knows what she’s doing?

Like, she’s tried reintegration exactly one time before, and the person she tried to reintegrate not only didn’t get fully reintegrated, but also fucking dropped dead. Reghabi is clearly just throwing shit at the wall, trying to see what sticks. It’s unclear at this point if reintegration is even truly possible, or just a false promise that she uses to have test subjects for her experiments. Hell, we don’t even understand her motivations at all.

I guess what I’m saying is that people give Reghabi a lot of benefit of the doubt that she actually knows what the hell she’s doing, and I think it’s highly likely that she doesn’t. True reintegration may just be a lie, and maybe it was never going to work for Mark anyway, or at least without killing him in the process.
