Even if we do extend ourselves in compassion and empathy for the one who took their life, and many do, it is still a self-centred desire to escape from pain.
This doesn't take away the justification for it. I hold to the opinion that it is justified that if one is in complete anguish for such a long time that to want to escape it by any means is totally understandable.
However most who suicides can possibly ever say they were thinking of others in doing so, with the exception of the incredibly ill who are in fact creating an immense pressure and burden on their carers.
At the same time yes it is also selfish for those to want someone to stay alive so that they do not feel the pain of their loss.
I think we have to be honest and realistic though that suicide is a final desperate attempt to escape suffering when no other recourse is seen as possible. And that's fine. We are pain avoiding creatures, we want to avoid it at all costs and yet when the pain is coming from the inside without cessation and without relief then it makes total sense that it seems that ending those feelings and negative voices through death is the only way.
I don't believe it is cowardly. Yet I do think it is desperate.
For the most part, the suicidal consider the feelings of those they will leave behind. For many, they willingly choose to remain on fire solely not to disrupt the people playing in the pool for as long as possible. Often at great expense to themselves. That demonstrates consideration of an intense nature. So they do have regard for others. Which is the opposite of the definition of selfish above.
This describes my point. The suicidal person who stays alive to not disrupt others is not acting out of selfishness. Yes they are carrying the pain rather than the others.
Once this person decides escaping their pain is of greater value to them than the deferred pain to others it becomes a selfish act.
I want to take the negativity out of the word though. I agree that by nature we are pretty selfish creatures. Let's not glorify or shirk the tragedy of suicide for what it is though.
It is at its core an escape from pain and suffering. Whether that is mental or physical anguish.
The person that acts is doing so for themselves.
It is also complex though. Debilitating physical illness and the burden this places on others starts to blur the lines somewhat, and isn't really what I'm talking about. That's a different ethical can of worms and should be treated differently.
I'm keeping my comments to suicide from mental/emotional anguish in an otherwise reasonably healthy individual.
I also am not holding the view around "you haven't tried everything you can" mental suffering is a very real and difficult thing to treat. Sometimes all options are not possible. Sometimes the suffering is so great that changes necessary to cope with or even enjoy life are not possible.
Suicide is an option. Its always an option. And yet it is still one that is determinant on an individual's desire for their own freedom from suffering. Ethically we can make comparisons like the ones to choices around consumption, etc, and I don't disagree with it.
Even being suicidal myself I'm hesitant to suggest in any way that it is a noble act. I'm also not saying it's a cowardly act.
Suicide is a desperate act. And it is done for one's own seeming benefit - an escape from suffering.
