Our righteous, reckless... TWITCHY little man. Who is the "real" Will? Is he good or bad? Neither one nor the other: we shouldn't label him (he's both).
Think of Will's mind as an antivirus (an impenetrable fort), he wasn't going to just let some lame or random killer seep into his mind, was he?
I used to think it was all because of Hannibal (and yes, at first) but then it was Will's doing. He kind of saw an opportunity for that long-awaited change with Hannibal and took it. That's fucked up, I know. But now I get why Hannibal said: "I can feed the caterpillar and I can whisper through the chrysalis, but... what hatches, follows its own nature and is beyond me." Back then I believed Hannibal was being delusional, but ohhh- it made sense.
