I am not attempting to control their behavior, merely offer a hindrance until another method can be found. As to placing burdens, I cannot control that, either. A member of Lacerta must die, which is a burden in itself. Allen, as well as the other members on Lacerta who also happen to be Blanks, will be burdened no matter who dies.
Can you define what is "normal" for Allen? Allen himself struggles to find a balance within himself. You state that you and he are similar in that you share entities within yourself, but are you so similar? Unless you share the same affliction, I daresay that you cannot speak for him just as I cannot speak for him. His responsibility does not lie with my conscious and willing decision.
