People who kill themselves by jumping in front of cars

No, it's not natural selection.
If it was, then cures for depression would not have come about. People would not seek help.
Suicide rates would be far higher if it was natural selection.

Shame about how you feel due to how you were treated as a child is natural, but it is not part of natural selection.

A genetic predisposition to depression can now be, in most cases, dealt with because we have evolved far enough to understand the causes of depression.
If you are going to play the evolution card, then perhaps you should take this into account.

Having a gene which dictates a psychological illness such as depression is the same as having a gene which will eventually cause any other kind of illness. A cure being developed doesn't change the fact that it's natural selection; we have developed treatments for countless diseases and disorders which could potentially cause the death of those affected.
Also, while I was not talking about depression brought on by traumatic experiences, the consequences of an outside influence can also be said to be natural selection, as the organism is susceptible to this influence.
For example, a number of birds of a certain species (I cannot remember which) had offspring with a red patch on their breast, due to being exposed to radiation around Chernobyl. The red patch was an unattractive trait to the rest of the birds of that species, and this trait eventually died out. This was given as an example of natural selection.

Yeah.. like driving.

If there's a chance you might die, will you still buy a car? You're missing my point I think.. about death not being a sign of discontinuation.

Well we'll put it simply then. Picture this:
Two attractive looking women. One of them has a great personality, easy to get along with etc.
The other suffers from depression and has deep rooted psychological issues.

Who am I going to pick? :pac:

Also, how is driving a trait? And how is it undesirable?
