I am sorry for your loss. You must remember that when someone chooses to take their own life, they are usually not in a rational state of mind. They indeed, do not think of those who are left behind to pick up the pieces. They are so caught up in the own misery, either real or imagined, that death seems to be the only solution. It is easy to say things like, "he could have asked for help...etc.", but when one reaches those depths of dispair, logical thinking is not the norm. I know, for I have been there. My attempt failed, so I guess one could call me a complete failure because I couldn't even kill myself correctly. Looking back, it was a stupid thing to do, but at the time, it seemed the best alternative. Do I still battle with depression, yes. Would I seek such a drastic resolution in the future, barring terminal illness, no. Unfortunately, your BIL, for whatever reasons known only to him, took this route. Try not to bear too much anger towards him. By all means, feel free to vent your anger here, we will listen. Get out the punching bag, and go a couple of rounds if need be. Try to forgive him, for your own sake, and do what needs to be done for the survivors. They will need much love and support in these times.
