Why do we look at death as a bad thing?

[Rahul]

-Why do we view at death as something bad?

Because normally it is a bad thing. Sometimes it's not like when someone is old, in great pain, and cannot be cured.

-When people die why are everybody so sad,how do we know that this life is really something good and death is something bad?

Because we'll miss them. In the absence of all life I don't think death is a bad thing. In a social species though, death is a very bad thing. You leave people behind without you.

-What is making us thinking that death is an bad thing,why don't we just accept it as a part of life?

We can both accept it and try our best to delay it as long as possible.

-Why are people so caught up in thinking what comes after death?

Ego probably. Or fear. It's hard to imagine a world without your existence. Superficially it's easy to imagine, but to really grasp it... well it's difficult.

Why does it seem that we want to live for ever?

I've known older members of my family that were ready to die in their twilight days. They were over the idea of living.
