why?

what should i say in my first blog....hmnp....the blog name is my demon. so should i talk about it.... OK well where did i get that thought? it came up to me when i was watching a show a "vampires diary" what if a person has a demon inside? a personality that so furious or so bad it will be called a demon. what if a person has this huge a emotion that he/she wants to let it out but it will destroy or ruin everything around it. what would it be like? d o i have 1? maybe, i think mine is not that but. my thoughts about this topic is still spinning. in my mind there full of  "what if". does sins consider a part of a demon? i thought it was but i think sins are demon inside a person, whether its lust, greed, wrath, envy, pride, gluttony, or sloth. its a demon that consume a man or a woman but 4 a reason the thoughts of having a demon inside us scares us a lot so i think thats why priest called it sins.
