No I'd never waste such an opportunity. How often have you been in a situation where you said to yourself "You know, if I didn't have a life and a future, I'd seriously consider taking out all those inconsiderate drivers". Now granted that's a rather tame example, and even being suicidal would still require a certain level of psychopathy. But how many people think to themselves "Somebody should really walk into Topeka with a high powered rifle and get rid of that Fred Phelps". Really, if you think you've got nothing else to live for, instead of just killing yourself you should at least make sure your death has some meaning. Whether that's removing the lowest variable bringing down humanity or calling 911 before hanging yourself so they can harvest your organs properly. There is a certain level of freedom that comes from hitting rock bottom.
