I think in most cases it is selfish, however deeply depressed people have no choice but to be very selfish most of the time. I don't think people are being intentionally selfish.
I think that's a good way of putting it.
At one point after my beloved mom died, I didn't care about life anymore. I was righteously depressed, I had something to be very sad about. I didn't have loved ones other than friends, really, no dependents, and it didn't seem like it would not matter if I drove into the Sound.
I knew that I needed to get out of town...get out or drive into that Sound. Then a job opportunity came up in West Virginia, so I got out of town!
Once I got out from the deepest of the grief (or rather, out of the all day every day part of the process...the grief still feels as deep, but it's not all the time, as you go further along) I realized that even though I had no dependents, I do have people who love me and would be very sad to see me go, especially so soon after my mom.
So during the time that I couldn't see that it would cause sorrow for others, YES, I was selfish, but I just didn't realize it at the time.
Hubby, before I knew him, hit absolute rock bottom, and it was actually a gun's misfire for the reason he's still around. As soon as the gun didn't go off, he realized what a selfish person he had been (and he sold his guns, a hobby all of his friends had been into since they were teens).
It was as though that moment lifted the depression he'd been living in (he had medicated, but the paxil caused even worst physical symptoms and made him MORE depressed...his MD wouldn't help him come off of them, so he endured getting off of Paxil cold turkey, but even those horrible symptoms weren't as bad as what was happening while he was on paxil), and he joined a gym, dropped a ton of weight, and he went forward from that. From that moment he realized how selfish he had been, to think that the pain inside was worse than the pain he would cause others, both to have him gone AND to find him dead.
I briefly read the thing about the guy in China, and it seemed that the guy chose a really bad spot to be "successful". It was only 26 feet, and while that *might* have killed him, I would think it would more likely just cause injuries he would have had to deal with for the rest of his life. Especially b/c they had an emergency air cushion there for him to land on...it was obvious that he was NOT going to actually be committing suicide by the...so to just drag it on was even worse than just going and doing it.
I know that sounds so heartless, but if you really put yourself at that scene...the authorities were there, there was nowhere where he was truly going to die (unlike that South Korean politician who jumped off a mountain the other day)...continuing on wasn't going to get him the results he seemed to want...and that was probably more selfish than the initial urge he had.
