What if Voldemort had a son, raised under different circumstances? well, here is the answer to such a question...as I am sure many people have asked this exact question...probably not, but that is not of my concern. Hope you enjoy.
....It is through his time in Hogwarts - and what Dumbledore ultimately has planned out for him - that sets Tom against his very nature. Tom posses a great darkness within, the monster inherited from his father and mother, but in tandem he too has the capacity for love; the want for love. A harsh upbringing in an orphanage would leave any wanting it. A most vital feeling to us all.
Throughout the book series, Tom wrestles with his own conscious, especially in the later books, as to which side he stands on. With his father? or with his friends? And when, eventually, Tom begins to serve both Voldemort's and Dumbledore's purpose laid out for him at the same time, his endeavours come at a terrible cost; shall he pick the task at hand, or save his relationships from damage beyond repair?
For if Harry Potter is the spear with which Dumbledore pierces Voldemort's heart, then Tom Marvolo Riddle is the shield with which capacity has given the spear the chance to strike.

...Because I have to say this; I am not sure if the image I used is free domain or not - if not, this is not my image so you are aware. As to whose it is, I have not the foggiest idea.
I hope this goes without saying, but I do NOT own Harry Potter in any way shape and/or form. All credit for the Harry Potter stuff rightfully goes to the author, JK Rowling.
