I am seeing some garbage takes out there so quick reminder:
Izzy himself doesn't hold a grudge for what happened to his leg because he fuelled the fire that took it.
Izzy knows he suffered the consequences of feeding the darkness and doubt and misery he saw in Ed.
If Stede's leaving led Ed to a cliff, Izzy was the friend who should have helped him and instead he shoved him over the edge and broke him. The man Ed has known longer than anyone in his life, his 'only family', severed the last hope Ed had that he was worth anything without 'Blackbeard'.
Izzy trained a shark to viciously kill... Blackbeard says you taught him everything he knows... tormented him in his weakest moment...This is Blackbeard, Not some namby pamby in a silk gown pining for his boyfriend...and then dangled his legs in the water. Naturally, the shark took his leg.
As Izzy says: 'Served me right, too'.
Which is why people being so furious on his behalf and acting like Ed is an abusive monster is to invalidate Izzy having any agency at all.
Do you also blame Ed for the murder of his father and think he's a bloodthirsty monster?
Or can you recognise that the cycle of abuse and violence corrupted and traumatized him and that his father shares a portion of the blame for his own death?
Perhaps it's more cut and dried in that scenario because people haven't imprinted on Ed's father?
Izzy is not blameless in the loss of his leg and he would be the first to tell you that. He is a complex human who has made mistakes and his whole arc this season was about him reconciling, owning his mistakes and being his true authentic self anyway. And he did it. Fuck yeah.
"BUT ED NEVER APOLOGISED".
Izzy wouldn't have accepted it if he had.
Ed said 'Sorry about your leg', knowing Izzy wouldn't accept a larger apology. His response was to 'fuck off' as it is. Izzy Hands will never accept a full apology or genuine word of kindness and he shut down Ed's attempts because he didn't want or need it.
Izzy's last act on the planet was to let Ed know he's sorry for breaking him. For feeding him to the darkness so he could have 'Blackbeard' to give him his purpose in life when really, Ed had needed a friend. He apologized to remind Ed that he is loveable just as he is. He wants to undo the damage he did.
To love a character is to respect his right to be a fuck-up and own his mistakes. And to let him learn to accept himself despite those mistakes.
This season made me love Izzy. And I am sad he's dead. And I love that he got to redeem himself, find family and a sense of belonging and help Ed heal when he couldn't always help himself to.
You can feel how you want to feel about the ending.
But to sit back and blast creatives for 'Doing it wrong' because you can't process your emotions without projecting it onto others?
Izzy would be disappointed in you, the same way he was disappointed in Stede for picking a fight with Zheng instead of handling his emotions about losing Ed.
