Tw: Mention of suicide
For all that Hannibal manipulates him I feel he's extremely emotionally dependent on will. He loses much of his smaller interests when away from will, still functioning but clearly much less content.
I do believe that if will died Hannibal would kill himself. I don't think he'd personally end his own life, but would spiral by killing more often and escalating, until he ultimately dies in an alternation with law enforcement.
His connection with Will became something he was incredibly invested in, finally finding some form of limited understanding that held potential for a form of honest acceptance.
I do think in the later seasons he views himself and Will as equals, despite the fact that he has destroyed Will's life and forced a desperate evolution from him.
