I think if you are emotionally invested in someone in any relationship, and that person becomes intentionally abusive and/or extremely neglectful, it can push you farther over or closer to the edge. What that particular "edge" really means depends on variables in the suicidal person's environment, current pressures, and feelings of whether it can get better or not.
I don't think she is entirely to blame, but probably 30 to 50% depending on how she abused him and if she was aware he was falling apart.
Every time my sister repeatedly becomes especially cruel and harsh, just like our father, I certainly feel even further pushed to the edge every time. I even tried to make obvious hints that I am/was/continuously suicidal , including saying things like I wish I'd never been born, or, if I could just hurry up and have a heart attack I wouldn't have to keep going through this nightmare, or maybe if i'm lucky i will just freeze to death if i become homeless in my car... She just continues to be brutal saying the most horrifying things that make me feel not only insulted and disrespected but make me feel even worse and more hopeless about how my entire life / existence with 95% either physically violent or extremely emotionally abusive family members but then she makes sure to give me little gifts like a bathroom carpet. Ohhh, yeah, carpets totally make abuse worth it *sarcasm*.
I wish/would rather have her love and support, like I could actually talk to her, but apparently that's impossible with the only family member i have left in this overwhelming exhausting world. That's another reason why even though I am on this forum, I'm actually a bit on the fence, as I can see both sides points as valid. I will never encourage anyone to ctb, but I also think it's their personal right in their decision for their own life. If anything, I try to be kind and try to give them some caring or at least sympathy.
My point is, especially if someone is already close to the edge, and you do something cruel to them, they likely want to die sooner and with a sense of more rushed urgency.
People who say That it's not their fault if someone committed suicide can be wrong; if you contributed to their pain and suffering that made them want to die the first place, you ARE partially responsible, even if it's only 5% out of 100, it's still adding to the very reason they "can't take it anymore".
In other words, if they already feel like they have a mountain on top of their head symbolically of pain, and you keep throwing on spoonfuls on top of the mountain of pain... especially if you know they're in pain and don't care... then that's a partial responsibility. The only possible exception being if that person is a direct threat to your personal safety and well-being, or if they themselves are abusive and you're trying to get them out of your life. So unless they are dangerous to you personally, why be cruel to someone who's already suffering immensely? I just think that's sickening.
People should try to be decent if someone is already depressed or suicidal, not cruel on top of it. Suicidal feelings are very overwhelming and should be taken seriously, people should be careful and be respectful to those in tremendous pain.
People also need to stop this brainwashed socialized NONSENSE acting like the only problem with suicidal people is that they merely have some type of "mental problem" when in fact we're just having a normal reaction to traumatizing experiences and/ or the most horrible and UNsupportive environment. People are not "just lazy" or "codependent" they are in PAIN and need goodness around them, not criticism and insults.
Think about it, if you know that they're already depressed and overwhelmed, and they're standing near the edge of a cliff, and you just go ahead and give them one push and they start falling off, are you not partly responsible for the final cruel push?
If you're cruel instead of kind to someone already down...
what does that say about who you are?
I think she should be held partly accountable if she was willfully cruel for no reason... especially if he reached out in his suffering for kindness and instead she just mocked him and in told him to go ahead and just off himself with no respect and no conscience, just cruelty... unacceptable.
Suicidal People should be treated gently...
