It's pure cowardice. It's saying that life is too hard to continue, and that they just want to give up. It means that they're more scared of living life than they are of dying. It's selfish cowardice, where a person says that they'd rather abandon everything and give up on everything than confront their life. It doesn't deserve respect, it doesn't deserve anything but an understanding of what mental breakdowns lead to such a decision. I will empathize with those close to someone who commits suicide, but those who choose to abandon the people that care about them and leave that burden on them will never get my respect.
You may say that I'm an awful person, but I'm just blunt. I'm more than willing to call a spade a spade, and call people like you out for your self-righteous bullshit. You're naive, and you don't know a damn thing about the world yet. The world is a mean, nasty, scary place, and you're lucky if people are willing to speak to your face rather than stab you in the back.
