Are you frustrated with the world, so bad that you won't give it a second thought to just fuckin' blow it away? Wait! Do not pull out your gun yet. Take a driver's helmet, hit the road, find a crowded place and start bashing up people with your weapon of destruction. What will happen is, the police won't interfere since, you're armed with a deadly fuckin' helmet. So they'll let you be and you can happily go about doing your act until a brave heart steps forward and attacks you. Let him do so. Once people understand that you are surrendering yourself to them, everyone will rush in and vent out their frustration onto you. Even a ten year old won't be afraid of you now. The 25-year old, who'd run away ten minutes back sighting the helmet in your hand, will come back in full force and start hitting you. Thus, you'll finally give everyone peace at your own cost. This is sacrifice. You might even die in the process, but worry not, you have helped today thousands of common men, by being their punching bag of anger, hate and disappointment. At least, for this one day, they'll go home happy and won't shout at their family members. At least for this one day, they won't get lost in some addiction to feel numb, as they won't need another escape.
Since, you've done some public service at your own cost, God the great might just forgive you of all your sins and past mistakes, and you'll be shown into the gates of Heaven. And since I've helped you attain salvation, the ultimate Judge might just forgive me of some of my sins and my chances to enter Heaven, just might have increased.
