But if your choices are because you suffer from a mental illness such as depression, should we as a society just "shrug" and say "Well, it's their choice, let them do whatever they want." ?

I don't think so - especially when a lot of times, due to their illness, they cannot make their own choice.

The problem starts when you get into "is this a state of mind or an illness?" territory. I've heard the argument that people who have the wish to commit suicide are by definition mentally ill and should therefore be prevented from doing it even if we don't know which mental illness they suffer from.
