Here's the problem: Hazou is a mid-level researcher at best. Necromancy is a legendary-tier project.
This is like the equivalent of an unremarkable physicist who only just got their degree last year solving entropy.
Now, said physicist did recently travel to the "free energy" dimension, and you might be able to scan some really useful data from him, but he's nowhere near as qualified for the job as the world-class multiple Nobel laureate specialist expert in entropy-reversal who lives three doors down.
Said expert is one of most predictable people you've ever met (he's an almost purely rational agent with a known utility function), is positively-inclined to the project, and might feel slighted (read: murderous) if you worked on such an interesting project to a successful degree but excluded him from it.
This isn't difficult, people. If you're that scared of him, talk Tsunade into going to the meeting with you.
