Then do it at home!
Don't go to the mall and take a bunch of us with you. We value life; you damn sycophant. Everybody's got problems. Every person you murder has problems that they are DEALING WITH. Some of those people are in situations so tough you'd think it was just a hollywood script. Our girlfriends have left us. Our parents suck too. We've gotten fired from our jobs before. Chill out.
Don't you know killing yourself is the stupidest form of getting attention? People will cry for five minutes and then you'll be forgotten forever. The worst solution!? It's the lazy way out of your issues. It's a sign of the ultimate drama queen. I don't care how bad you think it is now. Do not take your life. Yes, you're a moron. Yes, you're a failure. Yes, no one likes you; but only in THIS MOMENT. You still have the greatest power in the universe by your side; chance. You have a chance to turn things around. You have a chance to weather the storm. You have a chance to realize that you have the strength to get through it.
From a moral, ethical, societal, even economical point of view it's the worst thing you will ever think about. Don't even joke about it anymore.
But if you, in your infinite wisdom, decide to solve your problems the lazy way. Go hang yourself in your closet. Slit your wrists in the tub. Just leave the rest of us the hell alone. At least if you do it by yourself a few might feel sorry for you. If you go out guns blazing then you'll be remembered as being a troubled soul; and a consummate asshole.
Now eight innocent people are dead. For what? For what!? I think I'm gonna be sick. story
