Hannibal really didn't get beat up enough in the show, I think. He tormented Will so much but it feels like only half of it was what he did to Will and the other half was what OTHER people did to Will as a result of Hannibals actions.
Will feared walking into an institution and not being allowed to walk back out, and that came true thanks to Hannibal. He feared being psychologically dissected, noted, and studied - all of which happened in the BSHCI. He was put in a prime position to be poked and stared at, to have everyone ever who called him a freak be able to point at him behind bars and go "Look! I was right!". He questioned his own sanity because no one listened to him, and the one person that had was literally the one that put him there! His - dare I say first - friend who made him feel normal and not alone was literally the one to put him in the institute, to make people think they'd been right about Will Graham all along.
And he had to sit there through that, had to wonder if maybe everyone else was right, until he was sure it was Hannibal. But even that was little solace when he realised no one was coming to save him. It's why he turned to the manipulation so quickly and effectively, bc he realised no one else was going to get him out, he had to save himself and literally risk the death penalty while at it.
He had to sit for months through people gloating that they were right all along about how weird he is, at colleagues treating him like a stranger for crimes he didn't commit (and I will admit, it did not look good for him with all the evidence Hannibal planted & his altered mind state), through Alana saying she felt nothing romantically for him both privately and in front of a court. Beaten down already and then being made to feel like you're not even desirable, publicly, because it helps your case. To someone who already has trouble forming any sort of relationship - platonic or otherwise - and only has rapidly fraying connections while in the BSHCI.
And then when he gets out and no one even says the words 'I'm sorry' to him?? theres acknowledgements - I owe you an apology, I should've noticed - but no one actually says I am sorry. They just imply it. He had to sit through months of his worst fears coming true all while feeling like he's going crazy because no one else can see the truth (and it IS the truth!!) and then he doesn't even get real apologies and also now has his shit out there in the public being known as the guy that was arrested for being a serial killer.
So anyway. Hannibal deserves to get run over w a car is what I'm saying. And much more
