An innocent person crossing the street - as part of his quotidian lifestyle. Just stepping out of the kerb. And a van zooms by, at top speed...
BAM! It's over! The damage has been done. It is irreversible and there's, no doubt, nothing you can do about it anymore.
But at least have a heart - to take responsibility for what you've done. At least have a brain - to think rationally. At least have a sense of attention - for you are driving at night. At least know what your limits are, especially the speed limits on your van. And at least keep on a lookout - for whoever's crossing the road.
At least, at the very least, you should not have driven off. Where is your conscience?! Where is your soul?!
Your trip to the police station is not because you decided to take responsibility, but merely because you cannot escape anymore - too many people have seen what you have done and the catastrophe you have created.
You know that your arrest is inevitable. But you decided to turn yourself in anyway. To save yourself from the embarrassment? To save your dignity? Or to save yourself from being haunted from beyond the grave?
Nevertheless, you have destroyed someone's life. Just like that. You have robbed him of the chance to live to a ripe old age. You have robbed him of the life he has always lived.
Worst of all, you have robbed him from his family.
Let this be a lifelong lesson that will plague you for the rest of your life, reminding you not to be so impulsive, and reminding you not to be so indifferent. To teach you a lesson for not thinking about others. And to teach you a lesson for being such a thief - an irresponsible one too!
It is too late to repent. But it is not too late to learn.
