Do you think this is a good introduction paragraph? if not, tell me how i can fix it.

"i have a confession to make, i get obsessed very easily. so i wasn't too surprised when i became attached to sherlock. he was my hero for a little while, but i am slowly realizing how alike he is to the villains. he does have many redeeming qualities however, and i have yet to fear that his decisions are not for the better of people concerned. i would like to describe how he and a very notorious criminal, mr. stapleton of "the hound of baskerville" are both slightly insane, but i hope to show the distinction between them so you can discern the reasons that i believe sherlock is far from diabolical."
