You really can't engage meaningfully with Ed's story in S2 without firmly centring his mental illness and suicidality, because that's inherently what the story is: it's the story of a man having a severe mental breakdown and going to increasingly erratic extremes in order to achieve his end goal, which is to not be alive anymore...and then it's the story of his recovery from that.
And so much of my frustration with the way I see this being talked about (or, in many cases, not being talked about) reflects my more general frustration with how we talk about mental illness and neurodivergence, so buckle in because this got long (also I am going to be discussing suicide here, as well as very brief mentions of psychosis and ocd, so please take care).
There's this trend when we talk about mental health: we go 'oh mental illness isn't an excuse' or 'mental illness doesn't make you do bad things' or variations thereof. These are, in my opinion, some of the worst things to ever happen to the discourse around mental illness. It's reductive. Absolutely mental illness can lead you to do things that you would not have otherwise done, even things that you would be absolutely appalled by, if you were mentally well. What do you think mental illness is if it's not something that impacts your brain and how your brain functions? If your mental illness doesn't directly lead to problematic behaviour, then that's fantastic, but that experience is not universal. It's not an 'excuse' - it's an explanation for certain behaviours that's vitally important to acknowledge and understand in order to try and mitigate harm.
There's also this thing that happens with discourse around mental illness where we assume that what you do in the grips of mental illness is reflective of something that's innate inside you. You were violent whilst in the middle of psychosis? Oh, it's because you're an innately abusive person and this just reveals who you really are. You have Tourette's and one of your tics is a racial slur? Oh, it's because you're an innately racist person and this just reveals who you really are. Your OCD is rooted in a fear that you're going to murder your family? Oh, it's because you inherently do want to murder your family and this just reveals who you really are.
It's bullshit. What you do in your mentally ill state is not some deep philosophical reflection of your true character, and the idea that it is is something that causes really deep, dangerous harm to mentally ill and neurodivergent people.
So, now that that's over with, back to Ed.
Ed was behaving in ways that were acknowledged in canon as being extremely out of character whilst in the midst of a severe breakdown. Fang himself said that he'd 'never' seen Ed behave this way; even Izzy, who actively pushed for Ed to embody the extremes of his Blackbeard persona, ended up concerned because it became so extreme and out of character that it was impossible not to be concerned by it. The crew who mutinied on Izzy within a day didn't mutiny on him for months, not until their lives literally depended on it, because it's heavily insinuated that they were hoping he would get better. Because this wasn't the Ed that they knew (the Ed that we came to know in S1 - an inherently soft man who is caught in a culture of violence and is tired of it).
The show wasn't subtle about this. It didn't bury the lead. As well as the constant reminders that he was acting out of character in increasingly alarming ways, this was very clearly depicted as a breakdown, an almost total collapse of Ed's mental health. We saw Ed detached and numb and completely dissociated from the world around him. We saw him in private moments of despair, breaking down. We saw him behaving erratically in the grips of mania. We saw him display absolutely textbook warning signs of someone whose made the decision to die by suicide. We saw him smile and say 'finally' at the moment when he knew he was going to die.
The show basically painted a giant neon sign over his head flashing 'THIS MAN IS EXTREMELY UNWELL' in bright lights, and if you miss that, then it's because you're deliberately avoiding looking properly.
(And, important to note, that most of the people that I've watched the show with outside of fandom discourse absolutely took away from these episodes what the show was intending - they saw how unwell Ed was, they were devastated for him, and they desperately wanted him to get better.)
When Ed steered the ship into the storm, and threatened to put a cannonball through the mast, his clear goal was to create a situation where the crew had no choice but to kill him. I've seen people describe this scene as Ed 'trying to hurt the crew', and I think that's very much a misrepresentation of what the show was depicting. It was very blatantly a suicide attempt. He wanted to die, and he didn't care what he had to do in order for him to achieve that goal. That doesn't make it good behaviour, and it doesn't mean people didn't get hurt, but it does make it a very different situation than if causing harm had been his main intent.
There is a fundamental difference between 'he is doing this because he explicitly wants to cause harm to the people around him' and 'he's doing this because he's suicidal and beyond the point of being able to rationally consider who might be getting hurt in the process of ensuring that he ends up dead'. One of those is a bad person who enjoys causing pain - and the other is a deeply unwell person who can be supported and helped to recover and be better (and should be, for the good of themselves and the people around them).
And on that note, the failure to engage with this as a mental health story is also, I think, why I've seen some people get so upset about the show not doing Ed's redemption arc 'right' - because this isn't a redemption arc, and it's not trying to be. One day I'll do a separate post about how much I love that the show explicitly rejected a carceral approach, opting to essentially put him through community rehabilitation rather than punishing him, and even mocking punitive prescriptive measures (that rubbish youtuber apology speech was supposed to be rubbish and unhelpful), but that's one for another day.
The fact is that the show is telling a story about mental illness, and that inherently means that Ed's arc is a recovery arc, not a redemption arc. And if you're expecting a redemption arc, then you've fundamentally misunderstood the story that they're telling (and the revolutionary kindness at the heart of the show).
I have a lot of feelings about this because I genuinely believe that it was one of the best depictions of mental illness and suicidality that I've ever seen. Within the confines of it being a half hour, eight episode comedy show, they told a story about mental illness that was surprisingly realistic (with the obvious fantastical over the top elements of it being a pirate show - and piracy is explicitly depicted as a culture where violence is heavily normalised), and that didn't shy away from the messier, darker, more complex elements of mental illness (particularly of being suicidal).
And then, most importantly, after all that, the show took me gently by the hand said 'you are not defined by what you do in your lowest moment - you can make amends, you can recover, you are still loved, and you are worth saving'.
