If someone kills themselves, you're as ignorant as can be, and thus in my opinion that person does not matter whatsoever. If someone killed themselves that I was very close to, I would hate them for doing so.
Even still, that's directly effecting you. In fact, it would be hurting you immensely. Hatred is such a piety, horrid thing to waste any piece of life on. And just because a person makes a fairly ignorant, I suppose you actually could say, decision in many cases doesn't mean they deserve that hatred.
This is true, but jumping in front of a train affects more people than if you shot yourself in you own home.
It directly affects more. The indirect line of consequence is always the same, no matter what. :o
Even so, I'm talking on a basis of meaning. That is, a life is still a life, regardless, and each can hold an equal impact on the world.
