Screeching Creature

this is my character for a oc  Creepypasta  his name is Screeching creature A.K.A  S.C  i need help with his story but here it is 

Screeching creature was originally a demon snake and  is a 6'9 tall creature with thin legs and arms that are skinny reaching out to 10 feet long he is a snake demon, who was in Circus but the owner of the freak show circus threw him away when he was only a  little snake demon and the owner of the freak show said with the harmful words "no one will ever love a creature so hideous and mutated and so disgusting" then with one last look at the pitiful creature he got a knife and slashed at the little snake demon, when he was just a little......demon after all, and the little demon thought "what did i do wrong"he thought as he cried, S.C can talk but only when he wan'ts to be heard and when he feels threatened he lets out a deafening screech that will make your ears pop off, S.C is a very creepy demon but he can also be a friend, the only thing is, people are to terrified to get near or talk to him, So later on S.C found the woods and made that his home now all he can do is wait alone with no company no one to tell him from right and from wrong, no comfort, no love, but he remained in the forest repeating these words "Insanity is the key to a smile"
