Whether fear causes involuntariness simply?

Objections

Objection 1 : It would seem that fear causes involuntariness simply. For just as violence regards that which is contrary to the will at the time, so fear regards a future evil which is repugnant to the will. But violence causes involuntariness simply. Therefore fear too causes involuntariness simply.
Objection 2 : Further, that which is such of itself, remains such, whatever be added to it: thus what is hot of itself, as long as it remains, is still hot, whatever be added to it. But that which is done through fear, is involuntary in itself. Therefore, even with the addition of fear, it is involuntary.
Objection 3 : Further, that which is such, subject to a condition, is such in a certain respect; whereas what is such, without any condition, is such simply: thus what is necessary, subject to a condition, is necessary in some respect: but what is necessary absolutely, is necessary simply. But that which is done through fear, is absolutely involuntary; and is not voluntary, save under a condition, namely, in order that the evil feared may be avoided. Therefore that which is done through fear, is involuntary simply.
