was protecting Dexter and potential innocent victims out of love and the goodness of his heart.
was using Dexter and turned him into a killer to satisfy his own revenge fantasies.
It's complicated, but he mostly had Dexter's best interests at heart.
It's complicated, but his motivations were mostly shady.
Do you like Harry?
I thought it was pretty heavily implied that Harry used Dexter and that Dexter being a killer was his plan all along, rather than something he just dealt with exceptionally well (erm, for a while). Was that just my interpretation? I was surprised to meet people who had the same view of him I had at the beginning of season one. I definitely started out pro Harry, but couldn't really ignore what the show revealed about him as it went on.
Also, is there any difference in how Harry is presented in the books? I haven't read them.
