I wonder why he let Kaneki live. However, I do have a few theories.

Kaneki reminds Arima of himself in the past. I can imagine Aroma possibly having a past similar to our favorite protagonist. Therefore, maybe he pitied the half ghoul.

Or, he plans to use Kaneki. In what way? I'm not completely sure, but have the general idea. Arima may be, and most likely is, using Kaneki to end powerful ghouls (Eto, Tatara, Noro). Or, he plans to have the latter be his successor. After all, let's not forget that Kaneki actually landed a bit, even if it was a small scratch. Arima obviously sees some kind of strength within Kaneki.

These two clearly have some kind of connection that will be shown near the climax or perhaps the end.
