I don't. I feel happy for them that they managed to make it out. I do, however, agree with ijustwishtodie that the only lamentable part of hearing about suicides in the news is the suicide prevention bullshit. That shit makes me angry. But the rest, it's a positive in my eyes; a person is now free from their troubles and out of this Sisyphean hellhole. Sure, I haven't joined them yet, but it'll happen when it happens.
I used to be upset, until I realized just how powerful a foe SI can be for some people. There's a lot of people who just can't CTB, or simply need the right method in order to pull it off. I often hear from people online (and my close friend IRL) that the only reason they're alive is the survival instinct. So it's a reasonable explanation for one's continued existence (or at least until the right method falls into one's lap).
Everyone is different, and in this regard (CTB), it's unreasonable to compare yourself to others and then get upset when things don't match, imo. Sure, you likely share the same number of fingers on your hand as them, but are your circumstances the same? Is your nature/character the same? Is your mental state the same? Your past experiences the same? Your method the same? I'm not one to tell people not to hate themselves, because I am not them and I have no clue what it's like to be them. But from an outsider perspective, I think this is one of the more unwarranted reasons to hate oneself. But I don't know you or your situation, so maybe it is warranted on some level. I don't know.
