Suicide is very selfish. The pain it leaves those still alive is immense especially to family. It's especially damaging to minor children.
While what you say is true, I think, it certainly isn’t “all there is to know, or say” about people who make that choice. The tone of your post (whether intended or not) is judgmental. As though the person who commits suicide never considers the pain he/she will cause for others (or has and just doesn’t give a damn). You might consider this, that the pain that drives them to end it all is so great that even though they fully realize the impact of their action on people they love, they are still driven to an ultimate method of relief.
One of the lessons in this particular instance is that no matter how great someone’s life looks from the outside, nor how much real success someone has achieved, it isn’t sufficient as a “reason to live,” and in fact may contribute to a more ultimate sense of the meaninglessness of their life.
I don’t think we need to “respect their choice.” Everything in me would want to help them find meaning for their lives that would be a sufficient foundation for the future. But in the end, I do need to recognize the reality of their pain.
