I don't think that it's wrong, provided the person making the decision is in a stable state of mind.
In addition, I think that this should be taken further. I think that anybody who wishes to depart early should be allowed to do so, for any reason, even for no reason at all, provided they are in a stable state of mind and not influenced by an illness such as depression.
You had no choice in being brought into this world, so why should the choice of leaving it painlessly and quickly be taken from you?
Also, on a similar point to the OP, humans aren't "put down" to ease suffering because in many places it is illegal. It's not legal in the US (even though the US healthcare system effectively forces it onto people because of lack of funds, in some cases), most of Europe, or Asian countries. However, on a similar line of thought, patients have the right to refuse treatment, even if it is life-saving (I know, for instance, in the UK if you have cancer you can refuse treatment and instead request for everything to be done about pain, effectively deciding to "put yourself down", albeit unconventionally, but even this can't be truly painless).

For the uninsured in the US, I'm pretty sure that if the injury or illness doesn't kill you, the resulting bankruptcy will.
