Oh yes one more thing, anti alchemy doesn't affect Viles. =p 

Thier alchemic drive is already warped and hence can't get disrupted. xp There is a reason Viles are believed to be abominations. 

And here is some more food for thought, Insannadiction has three stages. First stage is "Infested". Usually a person tends to stay at this stage for quite a while before becoming a Vile (at which point what little humanity you had left is gone and you become a powerhouse mad crazy mofo). But interestingly Ben became a Vile unnaturally fast. =p

Oh and here is one more thing, Vile is only the second stage. =p
